Re: [R] rJava works with 32-bit but not 64
For what it is worth Spencer, I can start rJava in both 32-bit R and 64-bit R for Windows 7. [And could even before Simon fixed the error message). And yes, I have both 32-bit Java and 64-bit Java 1.7.0_13 installed. They should be separate entries under your control panel. Rob -- Robert W.

Re: [R] rJava works with 32-bit but not 64
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). 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. Rob -- Robert W.
