[R] Extracting SSE from lm

[Greg Snow]

It is not clear what you are doing or why you are doing it.  If you tell us your ultimate goal we may be able to help you find a way that does not require all the computing that you are doing.

How do you get your coefficients? Are you using lm? Have you looked at the resid function?
