Hi As you did not provide any piece of code I done some myself
x<-1:20 y<-5*x+3+rnorm(20) plot(x,y) fit<-lm(y~x) par(mfrow=c(2,1)) plot(x,y) abline(fit) plot(x, resid(fit)) I do not see any problem with this. If you want to set up margins use par(mar=....) par(mar=c(0,4,4,1)) plot(x,y, axes=F) axis(2) box() abline(fit) par(mar=c(5,4,0,1)) plot(x, resid(fit)) Regards Petr r-help-boun...@r-project.org napsal dne 28.09.2009 17:19:27: > Hello everybody, > > I am sure this is a beginners' problem which is being asked > recurrently every few months, but nevertheless I wasn't able to find > the answer searching through the r-help list. > > So here is my problem: I would like to plot a set of points (y vs. x), > a (linear) regression line through them, and on the second graph > underneath the first one I would want to plot residuals vs. x.
