[R] Problem with plotting diagnostics - Error in object$coefficients : $ operator is invalid for atomic vectors

[Manderscheid Katharina]

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

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
