[R-sig-Debian] How to have multiple versions of R on Ubuntu 8.04

[Michael Rutter]

Matthieu,

Have you tried installing it?  We have just updated the versions of R on 
CRAN and maybe the bug the package website mentions have been fixed.

In order to have multiple version of R installed, you will need to build 
the second version from source.  Here are the details:

http://cran.r-project.org/doc/manuals/R-admin.html#Installing-R-under-Unix_002dalikes

You must be very careful to install R in a different location and have a 
different location for the lib files.  Read carefully through the 
section of Unix-like systems to see which options you need to set.  The 
good news is that you can always reinstall R 2.10 from apt-get or 
synaptic if the versions cross.

Another option to consider is using a virtual machine (I use Virtual 
Box, which is open source) with the needed version of R on it.  You can 
share data files between the host and virtual machine, if needed.

Hope this helps,
Michael
