[R] R 64 and R: using 64-bit versions of packages in R (32)

I'm running R 2.9.2 build 5464 on OS X 10.5.8.  Having encountered  
memory allocation problems, I ran the problematic code in R64, the 64- 
bit version of the same build.  When I attempt to load openNLP I  
receive the error message that the 32-bit version that I had been  
using does not run in R64.

Assuming there is a 64-bit version, can I install and load it in R64  
and, when I subsequently switch to R (32-bit), will 64-bit versions of  
packages run there?  I'm trying to avoid constantly having to manually  
switch between 32- and 64-bit versions of packages.
