Hello:


       rJava works for me under 32-bit but under not 64-bit R; see below.


       Suggestions?
       Thanks,
       Spencer

Hello,

Do you have a 64-bit version of Java?

rJava says to you:
call: stop("No CurrentVersion entry in '", key, "'! Try re-installing 
Java and make sure R and Java have matching architectures.")

Regards,
Pascal

because it works with 32-bit R but not 64-bit R.


       Is it feasible to have both installed in a way that allows the 
each version of R to select its own version of Java?  A comment on 
stackoverflow suggests that may not be easy 
(http://stackoverflow.com/questions/5272216/is-it-possible-to-install-both-32bit-and-64bit-java-on-windows-7). 



       Thanks,
       Spencer

One of the simplest ways to be sure of getting 64-bit Java is to use the 
64-bit version of Internet Explorer which makes things almost automatic.
