[R] rJava works on R-32bit but fails in R 64bit

[Collin Lynch]

I'll echo this and expand.  Hui it is possible, indeed likely, that you
are running a 32bit version of Java.  In that case the error may be
attributed to a miscommunication between the two.

You can check you java version by running "java -version" in the command
prompt.  If it is 64 bit it will tell you.  If it does not say 64-Bit then
you have the 32-bit version and will need to change it.

	Best,
	Collin.
