Previously installed versions after installing 2.12

Max,

please consider reading the R for Mac FAQ (most notably 12.15) and the information displayed as you install R. The latter tells you that the default is to remove your old version and instructs you how to install multiple versions in parallel if that's what you want. The former explains why you need to change the "Current" version softlink if you want to switch between versions and there is even RSwitch app for that to be had at http://r.research.att.com

Cheers,
Simon

Everyone,

I have a few only versions in /Library:

drwxrwxr-x ?4 root ?admin ?136 May 13 23:46 2.10
drwxrwxr-x ?3 root ?admin ?102 Aug ?9 16:00 2.11
drwxrwxr-x ?6 root ?admin ?204 Aug ?9 16:00 2.12
lrwxr-xr-x ?1 root ?admin ? ?4 Aug ?9 16:00 Current -> 2.12

I need to check that something worked in 2.11.x, but when I run

$ ?/Library/Frameworks/R.framework/Versions/2.11/Resources/bin/R64

R version 2.12.0 Under development (unstable) (2010-08-08 r52687)
Copyright (C) 2010 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

Note the dates on the 2.11 and 2.12 paths are both Aug ?9 16:00, so
I'm guessing that the 2.12 installer over-wrote the 2.11 install.

I installed 2.11 again, did my testing, then re-installed with 2.12
pkg file dated today:

$ ls -al /Library/Frameworks/R.framework/Versions/
total 8
drwxrwxr-x ?6 root ?admin ?204 Sep 15 12:19 .
drwxrwxr-x ?8 root ?admin ?272 Sep 15 12:19 ..
drwxrwxr-x ?4 root ?admin ?136 May 13 23:46 2.10
drwxrwxr-x ?3 root ?admin ?102 Sep 15 12:19 2.11
drwxrwxr-x ?6 root ?admin ?204 Sep 15 12:19 2.12
lrwxr-xr-x ?1 root ?admin ? ?4 Sep 15 12:19 Current -> 2.12

It looks like it wiped out the 2.11 install again. I know that the
labels are "Under development" and "unstable", but it is worth brining
up.

The OS version is 10.6.4.

Thanks,

Max
