Well, I sought a statistician who showed me how to do this task using

You are certainly getting bad advice!
I am interested to learn how to
perform this basic task using r because it's free and and use linux.
That's ``R'' not ``r''.
The output from the lm() command using version 171 yielded the same
result as obtained from the statistician who helped me. In contrast
enabling the version 251 did not yield the same result, hence this
original post.
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,
