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

For sure this is not a Mac OS X related problem. If the data frame is named BSE then your lm() calls need to say data = BSE, not data = bse. How many factpr levels does company have? Besides all that, I would suggest you start with simpler uses of lm, and find out if they work.
