[R] "object not found"

I am not understanding the functions in R:

The following statements work OK if they are invoked in R:


But if they are enclosed in a function, then calling that function results
in the message:

  Error in eval(expr, envir, enclos) : Object "mm" not found

and no summary is printed for reg.  Are there other, more proper, ways to do
these?  Where in R's documentation should I be looking?

Thanks for any help/hints.
