I'm a new R user and, frankly, this problem has got me stumped.



I'm using the 64 bit version of RGui and followed the installation
instructions on http://www.rforge.net/rJava/



Here is the result:



package 'rJava' successfully unpacked and MD5 sums checked

library(rJava)


Error in utils::readRegistry(key, "HLM", 2) :

Error : .onLoad failed in loadNamespace() for 'rJava', details:

  error: JAVA_HOME cannot be found from the Registry

Error: package/namespace load failed for 'rJava'



I don't Have the faintest idea as t what I've done, or failed to do.



Assistance will be greatly appreciated.
