That's ``R'' not ``r''.

As was previously pointed out:
***THERE IS NOT SUCH THING AS VERSION 251 OF R!!!***
Nor is there a version ``171''.
You can find out what version you are actually using by
typing ``version''. For example, when I type ``version''
I get the following:
> version
_
platform i386-apple-darwin8.10.1
arch i386
os darwin8.10.1
system i386, darwin8.10.1
status
major 2 <------------
minor 7.0 <------------
year 2008
month 04
day 22
svn rev 45424
language R
version.string R version 2.7.0 (2008-04-22) <------------
(``Arrows'' <------------- added.) So the version of R that I am
running is 2.7.0.
cheers,
