Dear All,
Sorry for the trivial question, but if you are using Linux and want to
know the version of your installed libraries,

I think you mean the version of your installed *packages*, since R libraries do not have version numbers.



what are you supposed to do?
library() just tells you what R libraries you have installed on your
system, but not their version number.

For one package, you get an oveviwe using
  help(package="name")
or condensed
  packageDescription("name")
or more condensed
  packageDescription("name")$Version


For a list of all installed packages including version numbers:
 installed.packages()
