How to check the R version Quickly

In this tutorial, we are going to learn about how to check the currently installed R version in our system.

Using the R.Version()function

In the R language, we have a built-in R.Version() function by using that we can check the currently installed R version from a program.

Example:

v <- R.Version()
print(v)

Output:

$version.string
[1] "R version 3.4.1 (2017-06-30)"

Similarly, we can also check the R version by using a sessionInfo() function.

v <- sessionInfo()
print(v)

Output:

R version 3.4.1 (2017-06-30)
Platform: x86_64-redhat-linux-gnu (64-bit)
Running under: Fedora 26 (Twenty Six)

or you can view the R version by running a R --version in your terminal.

R --version
