Dear R-Help, I am using the 'mfp' package. It produces three plots (as I am using the Cox model) simultaneously which can be viewed together using the following code:
fit <- mfp(Surv(rem.Remtime,rem.Rcens)~fp(age)+strata(rpa),family=cox,data=nearma,select=0.05,verbose=TRUE) par(mfrow=c(2,2)) plot(fit) They can be viewed separately but the return key must be pressed after each graph appears (Click or hit ENTER for next page). I'd like to isolate the second plot produced (the estimated functional form of the influence of age on the log relative hazard) so that I can use the 'points' function to add the linear predictors for the untransformed and the log-transformed models. In the usual situation one would produce a plot and then type: coxfitu <- coxph(Surv(rem.Remtime,rem.Rcens)~age+strata(rpa),data=nearma) points(coxfitu$linear.predictor,col=2) coxfitl <- coxph(Surv(rem.Remtime,rem.Rcens)~log(age)+strata(rpa),data=nearma) points(coxfitl$linear.predictor,col=3) Can anyone tell me how to isolate just the second plot produced? Thank you for your help, Laura ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
