Thanks for the reply.

Yes, you are quite correct, but:

install.packages('rJava')

  There is a semi-colon in that path above that looks wrong. You might  
first want to check that all your PATH entries are recorded properly.

So, obviously, at this point I am attempting something that R does  
not like.

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) :

  Registry key 'Software\JavaSoft\Java Runtime Environment' not found

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

  Registry key 'Software\JavaSoft\Java Development Kit' not found

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

  call: fun(...)

  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.



Thanks in advance.
