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
