[R-SIG-Mac] Running older versions to test package

[stephen sefick]

Version are installed in || ?  I know where the versions are located
but I can not firgure out how to get them to crank up:

/Library/Frameworks/R.Framework/Versions/2.7/Resources/library

My problem is that I am having problems with the StreamMetabolism -
essentially relying on chron to work, and chron is not working as it
has in the past.  This issue has cropped up in the upgrade to 2.8.  It
is taking a much longer time to do things compared to 2.7.2.  2.3-25
chron under R 2.8 and 2.3-24 chron under 2.7.2.  I would like to be
able to run both of these versions side by side to try and find out
what has happened.
thanks for your help,
