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

[Manderscheid Katharina]

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?

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.
