[R-SIG-Mac] R 32-bit suddenly the default on Mountain Lion 10.8.2?

[Prof Brian Ripley]

Simon is pretty much off-line, which is why I replied.

I would simply set the R->R64 symlink as the installer would have done 
in SL and Lion.  The things will work as you expected.

Because I have so many flavours of R installed, I make my own links (in 
~/bin, which is on my path).

Actually, I think it needs to be future-proofed.
