Dear Dwayne, I didn't see your post until now, because our email system was down all day yesterday.
Mark Difford has already pointed your towards the cr.plots() and ceres.plots() functions in the car package. In your description of what you want to do, you mention the "adjusted explanatory variable." This sounds more like an added-variable plot than a component + residual plot (although the vertical axis of the AV is not the partial residual). In any event, AV plots are not recommended as diagnostics for nonlinearity. I hope this helps, John ------------------------------ John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of Culp, Dwayne > Sent: March-02-09 9:42 AM > To: R-help@r-project.org > Subject: [R] FW: partial residual plots > > I was advised someone might be able to help me with this. > > Very truly yours, > > Dwayne E.
