I have installed the latest versions of R (2.15.2) and Java (7.11), and through RStudio (0.97.310) I am trying to load the rJava package. It seemed to install properly, but when I call library(rJava) I get the following error:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: stop("No CurrentVersion entry in '", key, "'!
Try re-installing Java and make sure R and Java have matching architectures.")
error: object 'key' not found
Error: package/namespace load failed for ‘rJava’
The documentation for rJava makes reference to Java 1.5+, so I am wondering if I need to install an ancient version of Java to resolve this problem. Any help would be much appreciated!
Ok, I figured it out. Guess I should have read the release notes on the rJava development website. I had installed Java, but not the JDK. Once I installed that, everything worked fine.
I had this problem and solved it by downloading and installing Java 64-bit (which you should probably choose if you have a modern computer) from the Java download site.
