[R] Need help with lm function on MAC OS X. R version - 3.2.0

[samarvir singh]

Thanks a lot Don, I did the above mentioned. And yes one of my variable
field had some non numeric data. Because of large set of variables , when I
used str(BSE) , some result was omitted, so that's why it went un noticed.
Thank you
