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.
