[R] rJava works with 32-bit but not 64

Hello:


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


       Suggestions?
       Thanks,
       Spencer

[R] rJava works with 32-bit but not 64

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

Yes, that is the default. 32-bit R will only see 32-bit Java and vice versa,
because Windows separates 32-bit and 64-bit registries.

Ehm, it says "Yes, it is absolutely no problem. " -- which part of it
suggests it's not easy? SO is a good source of rumors, seldom facts -- but
in this case it's not too far from the truth.

Just a subtle bug in the error message if there is no Java installed (has
nothing to do with the architecture). Now fixed.

You got it almost right - it's slightly shorter than that:

install.packages("rJava",, "http://RForge.net")

but you know that if you ever looked at the rJava page ;)
