[Rd] directory structure of R 2.12.0 distribution
I am just revising my batch files which call R and have a question regarding the directory structure of the R distribution in R 2.12.0. Prior to R 2.12.0 the R executables were in R_HOME\bin but now are in R_HOME\bin\i386 on my machine. I assume that there is a different subdirectory of bin on 64 bit machines. Is that right? Is it always the case that there is exactly one subdirectory of bin and that the R executables are there? Or is it possible that there are more than one subdirectory in bin? If more than one is possible how do we know which one is the one to use? -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com
Hi,
On my 64-bit machine, there are two subdirectories:
i386
x64
I usually want to use the 64-bit executable. However, some packages
have not yet been compiled for a 64-bit machine, so for those I need to
use the 32-bit i386 subdirectory.

Is there something at installation time that says which to use? Is there a registry entry? Is this documented anywhere? -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com
