Sorry to not use your data but it's not in a form that lends itself
very well to quick testing. If you had included the input commands I
might have tried it.

Hi,
You have not given us all the data needed to reproduce your analysis
(what is SectionF?), but the issue is probably that lm.r is a list and
you're not treating it that way. Try
srt(lm.r)
and
summary(lm.r[[1]])
You may also want to look at the the lmList() function in the lme4 package.

Hello R list,
This is a question for anyone who has used the by() command. I would like to
perform a regression on a data frame by several factors. Using by() I think
that I have able to perform this using the following:
> lm.r <- by(master, list(Sectionf=Sectionf, startd=startd), function(x) lm
