How to find out which package version is loaded in R?

Question

I am in a process of figuring out how to use my university cluster. It has 2 versions of R installed. System wide R 2.11 (Debian 6.0) and R 2.14.2 in non-standard location.

Answer 1

Use the R method packageDescription to get the installed package description and for version just use $Version as:

packageDescription("AppliedPredictiveModeling")$Version
[1] "1.1-6"
