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. Thank you

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. For example, try lm( CP ~ company, data=BSE) If that works, then start adding variables on the right hand side until you get one that causes errors. The message about a 'closure' suggests that you are somehow asking lm() to perform analyses on an R function instead of data in a data frame. That would be very strange, and I have trouble imagining how that could be. Are you sure all your data is numeric? Try lapply( BSE, class) str(BSE) -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 5/14/15, 5:07 AM, "samarvir singh" <samarvir1996 at gmail.com> wrote:
I Have a data frame named BSE and CP is my independent variable and here;s the error I get if I try to run an lm function any idea whats wrong P.S - all my data is in numeric except company which is a factor. I have 2700 row and 450 variable P.P.S - I have no missing data, I have 0 in Empty field.
