I installed r language and r studio on my Fedora-20 system few months back. After that I got busy and now coming back to it. I wanted to know what my R version is, and I am unable to find any help on it. Is there any command/function I can use to find out version of r and rstudio?

There is a version command (not function) in R that provide a fulfilling overview on R environment and version:

    Its not really a "command" (R doesn't have those) its an object with class "simple.list", and the print method for "simple.list" is activated when you type its name and its printed as you show. You can get bits out of it such as `version$platform` as with any R list. – Spacedman Jul 01 '15 at 17:01

Type R --version at the linux command line.

You can use getRversion() or R.Version()$version.string to show info under R, if you want to check R version from Ubuntu you need to type:

dpkg -s r-base

When you start the R console, it should say across the top
