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.")
Simon, have you noticed there seem to be a bug in rJava about the
missing 'key' variable? The error message would be (slightly) cleaner if
the stop() call succeeded, wouldn't it? ;-)
A subtle bug which only appears with the 64-bit but not the 32-bit
version ... ?
Just a subtle bug in the error message if there is no Java installed (has
nothing to do with the architecture). Now fixed.
Great. How can I get the new version? [If it were on R-Forge, I could get it via
install.packages("rJava", repos="http://R-Forge.R-project.org";).]
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 ;)
Thanks. Unfortunately, I still have problems with 64-bit rJava: As noted
below, after your "install.packages", I get an error on library(rJava)
[which works fine for me with 32-bit R]. Thanks, Spencer

I agree: Thanks very much for your work. Spencer
Thanks for your work
I think I probably have a 32-bit version and not a 64-bit,
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?
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.
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).
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.
Cheers,
Simon
Thanks,
Spencer

Pascal
