How to separate linear regression plots in R ?

Question

For a linear model with 2 variables r = lm(y ~ x1+x2)

When I run plot(r) , I get a bunch of plots such as residuals vs fitted values and so on , but I can only look at one of them at a time . Isnt there a way to seperate them ?

Answer 1

A few ways. The most convenient is layout. ?layout for more details

r<-lm(y~x1+x2)
layout(matrix(1:4,2,2))
plot(r)

will produce a window with four plots.
