R version

One of the relatively easy optimizations available is to use an up-to-date version of R. In general, R is very conservative, so upgrading doesn't break existing code. However, a new version will often provide free speed boosts for key functions.

The version command returns a list that contains (among other things) the major and minor version of R currently being used.

Print the version details of R using version. (It's not a function.)
Use dollar indexing ($) to extract the major component of version and assign it to the variable major.
Likewise, extract the minor component and assign it to the variable minor.
