Script to have current R-devel (R-2.14) run side by side with R-2.13 on OS X

update-multi-R-links.sh

#!/bin/bash

## This script was originally written by Kasper Daniel Hansen on a post to bioc-devel
## in order to illustrate how you can have two versions of R running at the same time
## on OS X:

## This is posted without any guarantees that it will work, and will obviously have
## to be changed to different degrees as new versions of R come out.

# sudo sed -i tmp "s|R.framework/Resources|R.framework/Versions/2.13/Resources|" /Library/Frameworks/R.framework/Versions/2.13/Resources/bin/R
sudo sed -i tmp "s|R.framework/Resources|R.framework/Versions/2.14/Resources|" /Library/Frameworks/R.framework/Versions/2.14/Resources/bin/R

The lines that do "surgery" on the current/release version of R are intentionally commented out for now.
