I used to work in R 3.4.0 version. Hovewer, this version doesn't support such packages as keras and tensorflow.
I was adviced to upgrade my R version to the newest one.
I downloaded the most recent R version 4.0.2 from the official site, then ran the following code:
install.packages("keras")
library(keras)
install_keras()
And got the following error:
Error in install_keras() :
You should call install_keras() only in a fresh R session that has not yet initialized Keras and TensorFlow (this is to avoid DLL in use errors during installation)
After this, when I tried to quit R session by q() , I faced the following error:
Error: option error has NULL value
Error: no more error handlers available (recursive errors?); invoking 'abort' restart
Error: option error has NULL value
I've never faced such an error before. When I used old R version, I typed q() and then had to choose between y and n. No errors appeared.
I'm asking you to help to to solve this problem.
You need to create a new environment and then you can install R 4.+ in Anaconda. Follow these steps.
conda create --name r4-base
After activating r4-base run these commands
conda activate r4-base
conda install -c conda-forge r-base
conda install -c conda-forge/label/gcc7 r-base
Finally, you will notice r-basa version 4 will be installed.
Thereafter, you can install any supported packages. But with this only, you won't have the ability to use it in the Jupyter notebook. You need to install install.packages('IRkernel') and Jupyter notebook as well if you want to use it. Otherwise you are good to go with R-Studio.
For Jupyter Installation and RKernel.
conda install jupyter
Then open the R console. Write in R console
install.packages('IRkernel')
IRkernel::installspec()
Congrats! You can use Notebook for Python and R.
Find the location of R.exe on your computer. In my computer, this executable is at
C:\Program Files\R\R-3.4.3\bin
Open another Anaconda Prompt as Administrator and change directories to wherever R.exe is on your computer with cd file path. On my computer, it’s cd C:\Program Files\R\R-3.4.3\bin, but it might be different for you.
Then run R from within Anaconda Prompt in Admin mode with R.exe
You’ll notice that you’re in an R session. From here, run the following three commands into the terminal.
install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()
In order, they (1) install the devtools package which gets you the install_github() function, (2) install the IR Kernel from GitHub, and (3) tell Jupyter where to find the IR Kernel.
Open Jupyter notebook and enjoy your new R kernel!

#Rheatey Bash works perfectly. but i was facing python.exe this program cant start because api-ms-win-core-path-l1-1-0.dll python system error. this is a problem running on windows 7 but i resolved this issue by installing the kernel following https://richpauloo.github.io/2018-05-16-Installing-the-R-kernel-in-Jupyter-Lab/ and it works fine
I recently "upgraded" from OSX Mountain Lion to Yosemite and from R 3.1.3 to 3.2. Immediately after the upgrade, when I opened R or RStudio I got a pop-up message saying that I needed to install Java 6. In addition, loading rJava or any package that depends on rJava (e.g., xlsx) caused RStudio to crash (R also crashed when I tried this by opening R.app directly).
After trying a few fixes found on Stack Overflow and elsewhere (more details below), I am at a point where loading rJava or any package that depends on rJava no longer causes R to crash, but results in the following error:
library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rJava/libs/rJava.so':
dlopen(/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: #rpath/libjvm.dylib
Referenced from: /Library/Frameworks/R.framework/Versions/3.2/Resources/library/rJava/libs/rJava.so
Reason: image not found
Error: package or namespace load failed for ‘rJava’
However, if I invoke R from the command line and then load rJava or any package that depends on rJava, it seems to work (or at least I don't get any error messages).
I've tried a number of different attempted fixes, some of them a few times, and can't quite remember exactly what I did in what order (didn't realize this would be such a morass and wasn't really keeping track), but here's the gist of it:
Added the following to my .bash_profile (per this SO answer):
export JAVA_HOME="/usr/libexec/java_home -v 1.8"
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/server
Reconfigured java from the command line as follows:
sudo R CMD javareconf -n
Checked options("java.home") and discovered this was set to NULL. I tried setting it to the following (per this SO question):
options("java.home"="/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre")
Installed the latest Java Development Kit and reinstalled rJava from source (can't remember where I found that one).
At some point while trying all of these, I was able to load rJava without crashing R, but instead got the error message posted above. In addition, when I quit RStudio, it would seem to close normally, but then an "RStudio quit unexpectedly" message would pop up, indicating that the program had crashed while trying to close.
I finally decided to install Java for OS X 2014-001 (Java 6), as I seemed to be running out of options. Now, when I opened R or RStudio the "This software needs Java 6" pop-up message no longer appeared. However, I was still getting the .onLoad failed in loadNamespace() for 'rJava' error message posted above.
In reviewing some of the posts I'd already looked at, I noticed another SO answer that I'd missed before, which recommended opening RStudio with the following command line code that gives RStudio the correct path to java:
LD_LIBRARY_PATH=$(/usr/libexec/java_home)/jre/lib/server: open -a RStudio
That opened an RStudio window and I was also able to load rJava and packages that depend on it without getting an error.
Lastly, I tried running R from the command line (which I hadn't done before). It turns out that on the command line, loading rJava or any package that depends on rJava works and does not throw any errors.
So, I can now get rJava to work if I open RStudio from the command line with the code that gives RStudio the java path (as noted above). However, I'd like to find a way to fix the underlying problem, whatever it may be, so that RStudio can be opened in the usual Mac way, without needing a command line kludge. I'm also concerned that having an old version of Java installed could cause problems down the road.
Does anyone have any ideas about how to diagnose and solve this issue?
I had the same problem and went through the same steps as you. The final step to allow starting RStudio through Finder/Spotlight was to link libjvm.dylib to /usr/local/lib:
sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
-f flag is added to force overwriting existing file/link
On OSX El Capitan 10.11, the user doesn't have permission to write to /usr/lib. So instead, use the following command:
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
You can load the libjvm.dylib explictly, by run like
dyn.load('/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/jre/lib/server/libjvm.dylib')
library(rJava)
On macOS High Sierra (10.13.1) and Java Version 9 you have to use a slightly different JVM path (notice the missing jre folder in the path compared to the instructions for earlier Java versions):
sudo ln -f -s $(/usr/libexec/java_home)/lib/server/libjvm.dylib /usr/local/lib
You also have to notify R about the JVM:
MY_R_VERSION=$(Rscript -e "cat(with(R.version, sprintf('%s.%s', major, substring(minor, 1, 1))))")
ln -s /usr/local/lib/libjvm.dylib /Library/Frameworks/R.framework/Versions/$MY_R_VERSION/Resources/lib/
Following command works:
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
After that, in RStudio, loading rJava works through loading of the "xlsx" package.
library("xlsx")
P.S. #1 Environment: Mac OS X El Capitan 10.11.3+ with RStudio 0.99.491+ and R 3.2.3+. (I've now tested this also on macOS Sierra (10.12) and R.3.3.1.)
P.S. #2 I find that openxlsx is much faster and doesn't rely on Java to work, so I'm now using that package. Hope that helps others.
You should be able to use the CRAN rJava, without needing to recompile rJava or do any additional steps by linking the shared library to the R frameworks library directory.
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /Library/Frameworks/R.framework/Libraries
This is how I configured it working properly on two Macs running Mac OS X El Capitan (10.11.6):
Uninstall 'rJava' by issuing the following commands in a terminal window:
Rscript -e 'remove.packages("rJava")'
sudo Rscript -e 'remove.packages("rJava")'
Download and install the Java software from Oracle: https://www.java.com/en/download/mac_download.jsp
Add the following lines to /Users/<userid>/.bashrc using your favorite editor:
# Set JAVA_HOME so rJava package can find it
export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)/jre
Close and restart any terminal, R, and RStudio windows (to pick up the changes to .bashrc).
Run the following command in a Terminal window:
sudo ln -sf $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
Run the following command in a Terminal window:
sudo Rscript -e 'install.packages("rJava", repos="http://rforge.net", type="source")'
Here is the easy steps for it:
remove the rJava package: remove.packages(rJava)
close R
install latest Java on you mac
open terminal and type this command: sudo R CMD javareconf
Open R and install rJava with this command:
install.packages("rJava", dependencies=TRUE, type="source")
The image not found issue exists with a brand-new install on OSX High Sierra with the latest Java SE 10 JDK.
I was able to solve the path issue with rJava using the fix found on the rJava Github issues page: https://github.com/s-u/rJava/issues/78
R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers
Here what worked for me on MAC:
in your ~/.profile or ~/.bashrc add this line:
%export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home
1.1 % source .profile (or % source .bashrc)
% sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
remove.packages(rJava)
remove.packages(Rweka)
From the terminal enter this command:
%sudo R CMD javareconf
install.packages("rJava", dependencies = TRUE, type = "source")
install.packages("rJava", dependencies = TRUE, type = "source")
Load your library("rJava", "RWeka")
Best of luck.
Maybe another simple answer which does not touch your filesystem:
$ install_name_tool -add_rpath /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/server /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
(Substitute jdk1.8.0_131.jdk with your JDK path.)
Check the location of libjvm.dylib file.
Try this, in my case this worked:
dyn.load('/Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home/lib/server/libjvm.dylib')
library(rJava)
I went through all the troubleshooting I could find, then installed jdk-11.0.1_osx-x64_bin.dmg from: Oracle downloads
Everything worked perfectly after that.
Check the version of the library that was not loaded when you run library('rJava') and match it to the java version you need installed.
I noticed that 'rJava' is pretty strict about JDK version while loading in Rstudio. In my case (Mac OS. 10.14.6 - Mojave) I had installed jdk-13 which was tested against jdk-11.
I have linked my JDK version to a non-existent directory that was assumed to be valid by Rstudio (JDK 11):
sudo ln -sf /Library/Java/JavaVirtualMachines/jdk-13.jdk/ /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk
and suprisingly it works like a charm...
BTW., there was no problem to run 'rJava' following the previous instructions in native R.
Here you can download the legacy Java version 6 for El Capitan: https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
After doing so, the rJava package works for me.
This line below has solved the same problem I was having with rJava package as some others in this discussion did. I'm sure there are more than one solution to this problem and I sincerely thank them all for their contributions because sometimes one line like the one below saves a lot of time from going to trash!
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
Run the following on the command line: sudo R CMD javareconf
Several solutions above have mentioned this, but they also suggest that one remove and subsequently re-install the rJava package. I found those additional steps to be unnecessary.
You can change the reference in R by using the following command:
sudo install_name_tool -change /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/lib/server/libjvm.dylib /Library/Java/JavaVirtualMachines/jdk-13.0.1.jdk/Contents/Home/lib/server/libjvm.dylib /Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava/libs/rJava.so
I first encountered the error referenced here:
Installing rpy2 on windows
which is that I couldn't install rpy2 because '.sh' isn't recognized by the default windows terminal as a command. To get around that, I'm using a Git Bash terminal, but then I get the error mentioned here:
Installing the R interpeter and R as a shared library uder the same tree
However, the solution in that post is for a Linux install only (I think).
As I understood that post, I should navigate to the bin/ directory in R and run ./configure (which doesn't exist in my directory). Any thoughts on how to fix this error for a Windows install?
I am trying to install two packages in R (3.3.2): devtools and git2r. They are depending on the existence of zlib. This comes with macOS Sierra (10.12.3) and it's version 1.2.8 by default.
When I'm trying to install these packages I get the error below.
I've been trying a lot of things.
directly installing via CRAN in RStudio: no effect.
trying to locate zlib on macOS: can't find zlib.
installing via R CMD INSTALL git2r: no effect.
I notice someone has a similar issue posted on GitHub: https://github.com/ropensci/git2r/issues. There is no solution yet.
Does anyone here have an idea?
Thanks!
Sander

UPDATE: the same issue persists on macOS X 10.12.5 in combination with R 3.4.0 - the latter I need for DESeq2.
Solution...Mmm. Not really. I simply uninstalled R and all the packages, and than I reinstalled everything again. I installed R and RStudio via homebrew, following the instructions here: https://rud.is/b/2015/10/22/installing-r-on-os-x-100-homebrew-edition/.
Oddly enough: all issues disappeared.
UPDATE #1: this solution does not - obviously - work for the combination R 3.4.0 and macOS X 10.12.5. We need a solution for this issue.
UPDATE #2: I have discovered what I believe was the issue: a wrong path to the xcode command line tools.
sudo xcode-select --reset did the trick and now xcode-select -p points to /Library/Developer/CommandLineTools. And which xcode-select points to /usr/bin/xcode-select. Googling I discovered that it is not needed to install Xcode through the App Store as it states on http://railsapps.github.io/xcode-command-line-tools.html:
"On earlier versions of macOS, it was more difficult to install Xcode Command Line Tools. It required a huge download of the full Xcode package from the Mac App Store or registration as an Apple developer for a smaller Command Line Tools package. Mac OS X Mavericks made installation of Xcode Command Line Tools much simpler.".
i was having the same problem. i have a note 8(samsung). just go to GitHub and install zlib from there.
After installing Mavericks on my Mac, I'm not able to run Rattle anymore.
Because of compatibility issues between RStudio and 10.9 (http://www.r-bloggers.com/rstudio-and-os-x-10-9-mavericks/), I installed v 0.98.433 of RStudio and R 3.0.2
Tried to launch Rattle the normal way: none.
I tried in a different way:
I manually launched xQuartz to install GTK+
via R-Studio I installed RGtg2 and Cairo
Installed Rattle, launched it and I got 1 sec message from Rattle, before it disappeared, crashing R session.
I then tried going back to R 2.15.3 (using RSwitch), doing same procedure.
Rattle starts with no ricognizable character and a bunch of related error messages on the RStudio console, from Pango.
Problem is it is looking for a directory .../pango/1.6.0 that does not exist (I have /1.8.0).
Is there any one who came out with a working combination of R/RStudio/Rattle on Mavericks?
I have a course I'm going to teach on data mining next semester and I introduced Rattle as the core tool, but I need it running.
Going back to previous Mac OS is not an option, because students may have the latest version.
Any help would be highly appreciated
I believe that the problem is with the GTK2 and Cairo modules. After building a few packages from source, rattle works for me...
I have had difficulties with Cairo/GTK2 since Mountain Lion. I got crashes using Simon's binary packages for these. Note that I updated my system to Mavericks, so I have not tried this on a clean install... I also have Homebrew installed for building programs from source. I use the ATT binary installer for R (thanks, Simon) for most packages but build a few packages from source. There were some hiccups and I spent a lot of time searching with Google. Here is what I did:
One needs XCode and the Xcode command line tools installed. After you install XCode, you need to run
sudo xcode-select --install
to install the command line tools. Then install Homebrew according to directions from the web site... Install gtk+ and cairo with their dependencies with:
brew install gtk+ cairo
And wait quite a while for everything to build....
The first problem I had is that I couldn't build any R packages from source because of this error:
make: llvm-gcc-4.2: No such file or directory
Google to the rescue...
I needed to change two lines in Makeconf in /Library/Frameworks/R.framework/Resources/etc to
CC=clang
CXX=clang++
Note: the R Mac Tools page now says this should be:
CC=/usr/local/clang4/bin/clang
CXX=/usr/local/clang4/bin/clang++
LDFLAGS=-L/usr/local/clang4/lib
Then download the source packages for RGtk2, Cairo, and cairoDevice. I do all the work in my ~/bld directory with:
cd ~/bld
export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:/Library/Frameworks/GTK+.framework/Versions/Current/Resources/lib/pkgconfig:$PKG_CONFIG_PATH
R CMD install RGtk2_2.20.25.tar.gz
R CMD install Cairo_1.5-2.tar.gz
R CMD install cairoDevice_2.19.tar.gz
Hope this helps.
