Thanks for your answer. I tried to use:
plot(fitted.values(model),rstandard(model),
xlim = c(55,90),ylim = c(-2,2.5))
This works for this plot just fine. But how do I get different axes for
plot(model,1) (meaning the plot including the red line)?
When I try the xlim and ylim arguments like this:
plot(model, 1),
xlim = c(55,90),ylim = c(-2,2.5))
I get this error:
plot(model,1),
Error: unexpected ',' in "plot(model,1),"
+ xlim = c(18,25),ylim = c(-0.5,1.5))
Error: unexpected ',' in " + xlim = c(18,25),"
