Re: How to install R 2.2.0 Debian 'unstable' package in otherwise 'sarge' system

Sometimes newer versions of programs can be found as "backports". I've never had any luck finding them, however. I think these are versions that have been put in unstable or testing and someone kindly generates a .deb for the stable environment. See what you can find about backports.

I would like to install the latest version of R (the statistical computing software). This is package r-base version 2.2.0 and is in the debian 'unstable' repository. Otherwise my system has 'sarge' packages, including r-base 2.1.0. What is the best way to do this? If I don't want to upgrade to unstable, must I compile R myself, or is there some way to install this as a debian package? 

I have tried:
(i) pointing /etc/apt/sources.list at unstable, apt-get updating and then apt-get install r-base. This results in 

[... full output at bottom of email ...]

E: This installation run will require temporarily removing the essential
package e2fsprogs due to a Conflicts/Pre-Depends loop. This is often bad,
but if you really want to do it, activate the APT::Force-LoopBreak option.
E: Internal Error, Could not early remove e2fsprogs

which scares me into desisting with this course of action.
(ii) apt-get install -t unstable r-base, but it replies that r-base is already the newest version. Have I not invoked this command correctly, or does the -t switch not do what I was thinking it did? 


Thanks very much for any help,

Dan
