R help - Jul 2003 - Version Number of a Package

Hello,

Apologies if this is a stupid question.  I googled and skimmed the archives and 
didn't see anything specific about this.

I am documenting an analysis procedure in a DB and I would like to know the 
specific version number of each package that I use.  Is there a standardized 
way of getting that information out from R, or should I parse it out from the 
source-code files?  Ideally I would like a function like this:
myVerNum <- Version(package.names);

Any guidance, direction, or suggestions are very much appreciated!
Paul

There are a several ways to skin that cat.

A few that come to mind are using package.description():
> package.description("Biobase")["Version"]
 Version 
"1.3.27" 

You can also use installed.packages():
> z <- installed.packages()
> z[1,"Version"]
[1] "1.2.28"

Also, in the Biobase package in Bioconductor (www.bioconductor.org),
there's a function package.version():
> package.version("Biobase")
[1] "1.3.27"
