R: rJava package fails to load

Question

I've installed the rJava pack successfully. However, when I run the command library(rJava), I get the following error.

 > library(rJava) 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’

How can I solve this issue?

I had this problem running XLConnect as well. It turned out that my instance of R was unable to see the Jave Virtual Machine on my 64 bit Windows computer at work. I simply found the 64 bit version of my jvm.dll file in the folder where it lives.

You can just at the path to that .dll file to your library or require() function and it should undo the madness, although, in my case, I had to update Java completely because it was too old and set this at the beginning of my script to point to the JAVA home.

Sys.setenv(JAVA_HOME="yourpathhere")

See if that works.

Bethany I don't seem to have that file in my computer... Do you know the best place to get it, and where I should install it? Do I need to install a Java compiler? – An old man in the sea. May 01 '16 at 16:09
If you search and do not have it, probably you will need to install the 64 bit version of Java completely. We had to do this at work. Give it a shot, go to oracle and download and install the most recent stable version for 64 bit. – sconfluentus May 01 '16 at 16:15
I'll do just that. Keep you informed. ;) – An old man in the sea. May 01 '16 at 16:55
How did it go with the installation? Did it resolve your issue? – sconfluentus May 06 '16 at 01:17
Hi Bethany, afterwards I remember that since my data is also on stata, it would be easier to just use read.dta., instead of opening it through excel. – An old man in the sea. May 06 '16 at 14:10
