Dear Jia-Chiun Pan,
First of all, why install an older version of R? In my experience the
backward compatibility of R is quite good. So using R 2.10.0 should be
ok. But if you really want this you can build R from source. The source
can be downloaded from CRAN:
http://cran.r-project.org/src/base/R-2/R-2.7.2.tar.gz
Extract, ./configure, make, make install and you have R 2.7.2 installed
on your system.
cheers,
Paul

Dear list
This is much like a linux problem, but I can't find any
reference for it. My OS is ubuntu 9.04 and a version of 2.9.2 of R has
been already installed in. Now, I need to install the version of 2.7.1.
I google a lot of websites and it seems like without a painless way
provided me to do it.
If any one offers me some suggestions/reference, I will
appreciate.
Jia-Chiun Pan
