I'm working on a project on R studio and I got a error message while installing qdap on my mac and running the library function.
And this is what I got.

I found that the problem is that R is not able to locate Java_home correctly.
Steps to follow:
Download and install Java JDK if you haven't already done so.
In Terminal, find java location by typing which java
Set JAVA_HOME in R as Sys.setenv("JAVA_HOME" = 'your java location such as /usr/bin/java').
Try reinstalling the packages openNLP, rJava, and qdap.

I'm trying to install the Homals package - library(homals), but keep getting this error message:

I have a couple of my colleagues to run the same code, the same thing happens. I have re-install R studio to the newest version.
install.packages("rgl")
install.packages("homals")
library(homals)
Any solutions for this? thank you.
I was able to successfully install on both Windows and Mac. I believe the root cause here is that you have R version 3.3 installed when you require at least v3.5.3 as per below:
library(homals)
Warning message:
package ‘homals’ was built under R version 3.5.3
I am using macOS Sierra and R version 3.4.0.
I installed the package "rJava" using RStudio:
install.packages("rJava")

R, rJava and Java are little bit messy in macOS. In general, you have to make sure to properly configure all the elements. There is a clash between Oracle's and Apple's version.

I'm trying to install an R package called ChemoSpec and am receiving the following error:

I'm running R version 3.3 using R Studio on OS X 10.10.5
Any help would be great! Thanks.
The problem is almost certainly that you do not have X11 installed. This in turn prevents rgl from installing, and in turn, ChemoSpec. Macs used to ship with X11 installed, but since OSX 10.6 they have not (info). You can install X11 from here. After that, try:
install.packages("rgl")
and if that is successful, do:
install.packages("ChemoSpec")
and you should be ready to go.
Any ideas how I can install RTidyHTML when I get the following error message?

You need to install XCode on your Mac if you want to compile from source. (Roman's comment only applies to Windows machines.) I just tried installing it on an XCode-equipped Mac running R 2.13.0 and get first a warning during compliation
ld warning: in libtidy/libtidy.a, file is not of required architecture
installing to /Library/Frameworks/R.framework/Versions/2.13/Resources/library/RTidyHTML/libs/x86_64
... and then get an error during the test load that is part of the install script:
Error in dyn.load(file, DLLpath = DLLpath, ...) :

I suppose it is possible that it may compile under a 32 bit version of R on the Mac.64-bit. See Simon Urbanek's web page: for more specifics and some installers for other packages.
EDIT: Installation while running 32bit R from the GUI was successful with a current R (version 2.13.1 RC (2011-07-03 r56263) )
I am installing rJava on a 64bit machine, running Windows XP, and am encountering the weirdest message. Below is the log. Has anyone seen this before? Thanks in advance.

Looks like a garden-variety binary incompatibility to me.
The NAMESPACE is a red herring as it happens to load the dynamic library, and that's where the trouble lies.
Does the DLL file exist at that path? If it does, than maybe it's one of its dependencies that's missing. Try http://www.dependencywalker.com/ to identify which one.
After that...?
