Q: Rstudio (latest) broken on Windows 8 x64 (object RMD5 not found)? - r

This the the error I get when I try to install or update any packages within Rstudio (latest version) on Windows 8 x64:
"Error in install.packages : object 'Rmd5' not found."

Try running the install or update in straight old R 64 bit version.
If you can make that fly. I would install installR using R 64 bit (NOT STUDIO) you can then use that to update any and all packages and versions of R pretty effortlessly. It manages dependencies and errors well.

Exporting excel files from R in windows [duplicate]

I am trying to load the rJava using the command:
library(rJava)
But I get the following error:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: JAVA_HOME cannot be determined from the Registry
Error: package or namespace load failed for ‘rJava’
I tried reinstalling both the Java and the R program with the latest versions
but still get these errors..
May I know how I can resolve this? Thank you very much!
This error is often resolved by installing a Java version (i.e. 64-bit Java or 32-bit Java) that fits to the type of R version that you are using (i.e. 64-bit R or 32-bit R). This problem can easily effect Windows 7 users, since they might have installed a version of Java that is different than the version of R they are using.

Install 64 bit Java from https://java.com/en/download/manual.jsp.
Then in windows cmd run
setx PATH "C:\Program Files\Java\jre1.8.0_211\bin\server;%PATH%"
(make sure your path is correct).
Then in RStudio run
Sys.setenv(JAVA_HOME="")
Now, you should be able to run rJava!!
I got the same error resolved by installing same version of R and Java i.e. 64 bits and manually updating the path i.e. ,
Sys.setenv(JAVA_HOME='C:/Program Files/Java/jre1.8.0_121') # for 64-bit version
R for Windows installer installs by default both 32-bit and 64-bit files. Reinstalling R and unticking 32-bit part solved the problem for me.
Under Windows 10, first check your (running) R-Version:
R.version
If you see something like x86_64, a 64-bit version of Java is needed.
Simply downloading and installing the matching Java version (https://java.com/en/download/manual.jsp) solved the problem for me. No reinstall of R needed (as suggested by other users here). There also was no need to set the path explicitly.
As mentioned in the r-statistics link cited above, you have to manually download the 64-bit version of Java. If not, then the 32-bit version will be installed.
So, if you have a 64-bit operating system, then ensure that both R and Java are using the 64-bit installs. Otherwise, this problem will persist.
This has been killing me and I have tried multiple methods above, it doesn't work. After, I mix all solution to try and below process works for me.
Install Java for 64 bit
Run below code in windows command
setx PATH "C:\Program Files\Java\jre1.8.0_171\bin\server;%PATH%"
(please change the address acorrding to your dvm.dll real address)
Run below in R studio
Sys.setenv(JAVA_HOME="")
Then I finally can run
library(rJava)
library(xlsx)
I faced the same issue and was feeling very down as I couldnt get my analysis done.
This worked for me :
check your operating system. 64 bit or 32 bit.
https://helpx.adobe.com/x-productkb/global/determine-whether-computer-running-32.html
uninstall previous versions of Java.
delete rJAVA library from Doc>R>win-library. If you have more than 1 versions of R, make sure you delete rJAVA package from all of them.
install Java based on system requirement (64 bit or 32 bit).
and finally restart R before and after installing rJava package.
If R is 64-bit version make sure to install Java 64-bit version!
If R is x86-bit version make sure to install Java x86-bit version!
You can add INSTALL_opts=c("--no-multiarch") to your install_github() call:
devtools::install_github("mne-tools/mne-r", INSTALL_opts=c("--no-multiarch"))
For more info: https://github.com/mne-tools/mne-r/issues/5#issuecomment-489588267
Create a new directory in C: drive as "library"
set your libPath this directory. you need to type
.libPath("C:/library")
reinstall packages which requires java (xlsx, rJava, RJDemetra)
it will give error message again but it will work.

Unable to install DeployR Open 8.0.0 on Windows 10

I am trying to install DeployR Open 8.0.0 on Windows 10 (64 bits). I have installed the following dependencies:
JRE 8
Revolution R Open 3.2.2 and MKL (RevoMath 3.2.2)
DeployR Rserve 7.4.2
I followed the install instructions for RRO & MKL and DeployR. I have also done a clean install, that is prior to installing all these stuff, I uninstalled R, and RStudio.
However, when start installing DeployR Open 8.0.0 (even as Administrator), it is unable to find the dependencies/prerequisites, and on clicking next it opens this page, which more or less talks about the same set of dependencies.
Here are the screenshots:
I am not sure what I am missing here. Please suggest.

How to install BigMemory and bigrf on windows OS

I have been trying to install bigmemory on my R installation.
My OS is windows 7 64 bit and I have tried it on R V2.15.1,2.15.2 and 3.0.1 64 bit but I cant get it to work.
I have tried several options
download the current source and run the command in R v3.0.1
install.packages("D:/Downloads/bigmemory_4.4.3.tar.gz", repos =
NULL, type="source")
but this gives an error "ERROR: Unix-only
package"
download older sources and run a similar commands, in the various
installations of R V2 V3 etc,
This gives me an error "ERROR:
configuration failed for package 'bigmemory'"
Any ideas? I am actually trying to install bigrf but bigmemory seems to be a dependency. Is there any workaround for this?
Many thanks
Seems the github version installs OK on Windows:
install.packages(c("BH","biglm"))
library(devtools)
devtools::install_github('kaneplusplus/bigmemory')
library(bigmemory)
the package authors told me they are fixing the CRAN one to work on Windows again too.
Going to the CRAN page here, shows you that you have to compile the sources on windows. Google how to do it or look at official document : here
Of course if package A depends on B you have to install B before A yourself.
EDIT: actually it says OS_type : unix

Unix-only package error in R

I'm trying to build the R package bigmemory for Windows 8 x64. However, when running R CMD INSTALL --build bigmemory_4.4.3.tar.gz, I receive the error ERROR: Unix-only package. I do not know why this is happening, but my guess is that it has something to do with the configure file of the package. I'm using R 3.0.1, 64 bit.
See this link, Windows support has been suspended. It's not your R-version, if you want to make use of it you'll have to use cygwin or install a Linux partition. You can also try the package ff.
The bigmemory NEWS, says "Windows support is temporarily suspended due to issues with the Boost headers." for the most current version of bigmemory.
The package you mention in the comments doesn't depend on a specific version of bigmemory, so you could try to build one of the older versions of bigmemory from the archive.

Can I use rattle on 64-bit R?

Trying to install rattle on a windows server 2008 R2 64bit machine, using 64-bit R ver2.11, I got the following message:
install.packages("rattle", dependencies=TRUE)
Warning: dependencies ‘RGtk2’, ‘rggobi’, ‘RSvgDevice’, ‘Biobase’, ‘multicore’, ‘marray’, ‘affy’, ‘snowFT’, ‘Rmpi’, ‘rpvm’ are not available
When I tried to install one of them:
install.packages("RGtk2")
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘RGtk2’ is not available
Finally I noticed this and this. Should I go back to 32-bit R in order to use rattle?
Thank you
I was trying to use Revolution R for Windowswith Rattle, was told currently RGtk2 is not available on 64 bit, but the next release (in April or so) will support it
Why not 64-bit Linux?
