this problem seems to only exist in R 2.12.0 but not in R 2.11.1.
any ideas? a bug?
Duncan *did* say that he was using R 2.12.0. So that's not likely
to be the problem. Most of the time, when users claim that a
problem exists in a new version that did not exist in an older
version, it's due to a change in the user's setup or to not
updating packages or to not checking the NEWS file.
Since you still have not provided a *reproducible* example,
it's not likely that anyone can help. Can't you make up a
small example that shows exactly how you are using lm()
and that will generate the error?

hi all,
after fitting a multiple linear regression
model<- lm(y ~ a + b+ c+d)
i wanted to plot diagnostics
plot(model)
but get the error message
Error in object$coefficients : $ operator is invalid for atomic vectors.
which does not make a lot of sense, since there is no "$" - i am working with
an attached dataset.
can anyone help, please??
thanks a lot,
kat
I just tried those lines (with fake data for a,b,c,d and y) and got no error
message. I was using R 2.12.0.
I think you need to show us a reproducible example, and the
sessionInfo() to go with it, to help with this.
