Marc,
Start with 'which R', or run /usr/bin/R explicitly. That should be a
symlink to
/Library/Frameworks/R.framework/Resources/bin/R
and that should be a symlink, If it is not like
lrwxr-xr-x 1 root admin 3 28 Oct 08:03
/Library/Frameworks/R.framework/Resources/bin/R@ -> R64
or is linked to R32, change it to point to R64.
It is the installer which determines what it links to. Specifically
https://svn.r-project.org/R-dev-web/trunk/CRAN/QA/Simon/R-build/packaging/leopard/scripts/postflight
.
If running /Library/Frameworks/R.framework/Resources/bin/R64 is not
x86_64, come back to us.

Hi All,
I am on a fully updated MacBook Pro, running 10.8.2. I get:
uname -m x86_64
from the terminal, as would be expected.
I have been using the CRAN OSX binaries for some time now, rather
than building from source, which I had been doing previously.
Somewhere along the way in the past few weeks, apparently since I
installed R 2.15.2, the default architecture under which R is running
is now 32 bit, not 64 bit, which was the case previously. I just
noted this today due to some funny encoding issues that I had not
seen before and have spent the past few hours trying to figure out
what changed.
I initially thought something was amiss with the latest 2.15.2
release .pkg file. I completely removed R (Framework and symlinks to
the startup scripts, etc.) and re-installed. Same thing. 32 bit R was
the default link from 'R'.
So I removed R again and re-installed 2.15.1 (getting the older
binary from CRAN), since that was the last version of R that I had
installed which defaulted to 64 bit.
Funny, same thing, it defaulted to 32 bit R.
Then I wondered if there was something related to some anti-virus
software (Avast) that I had recently installed due to some events
that had occurred recently. I completely removed the AV software,
rebooted, removed R and then re-installed R. Same thing, 32 bit R as
the default.
What am I missing here? What is the installation program and/or the R
startup script itself looking for that determines whether 64 or 32
bit R should the default when one simply uses 'R' to start it up? A
read of the R startup script suggests that the output (as above) of
'uname -m' being 'x86_64' may be all that is needed, but perhaps I am
missing something else.
I am also attaching the full installation log file here (for 2.15.2).
I did not see anything there obvious to my eyes.
I can't recall the timeline well enough right now to consider whether
some OSX update changed something, or if there is something strictly
unique to my MBP that is causing this problem.
Thanks for any insights.
Regards,
Marc
