How do I check version of R language installed on my system?

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:

> version _
platform x86_64-w64-mingw32
arch x86_64
os mingw32
system x86_64, mingw32
status
major 3
minor 2.1
year 2015
month 06

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
