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

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)
