	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,
