R help - Nov 2010 - Problem with plotting diagnostics - Error in object$coefficients : $ operator is invalid for atomic vectors

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.

hi lexi 
indeed, for a week or so i can also plot the diagnostics - same script, no
change in data... maybe an update of a package, i don't know.

Dear Katharina,

I would like to confirm what Duncan found - i.e., R 2.12.0 is able to plot the
diagnostics without a problem.

this problem seems to only exist in R 2.12.0 but not in R  2.11.1.
any ideas? a bug?
