Dear Wendy, This must be the scatterplotMatrix() function in the car package. If I understand correctly what you want, the following should do it:
scatterplotMatrix(~ income + education + prestige, smooth = FALSE, data=Duncan, diagonal="none", reg.line=function(...) abline(0,1), xlim=c(0, 100), ylim=c(0, 100)) (The reg.line argument must be a function.) I hope this helps, John -------------------------------- John Fox Senator William McMaster Professor of Social Statistics Department of Sociology McMaster University Hamilton, Ontario, Canada http://socserv.mcmaster.ca/jfox > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of Wendy > Sent: December-06-11 10:46 PM > To: r-help@r-project.org > Subject: [R] questions about scatterplotMatrix > > Hi all, > > I want to plot some data with scatterplotMatrix.
