No, that's up to the user. If you want to run 32 bit R, use i386. If
you want to run 64 bit R, use x64. (You need to be on 64 bit Windows
and to have chosen to install both to have this choice.)

There's an entry in the 32 bit registry if you install 32 bit R, and one
in the 64 bit registry if you install 64 bit R. Writing R Extensions

It was announced in the CHANGES file, and there's a description in the R
Admin manual as well as the Writing R Extensions manual.
