Dear all, I am stuck with the following problem: Using the Indometh data set I want to plot the predicted values of a simple bixeponential model together with the observed concentrations. I managed to plot the predicted values: datafi<-Indometh fm<-nls(conc~SSbiexp(time,A1,lrc1,A2,lrc2),data=datafi) yhat<-predict(fm) datafi<-data.frame(datafi,yhat) xyplot(yhat~time |Subject,data=datafi,type="l") but how can I superpose the observed concentrations? Thanks a lot for your help Cheers Peter -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Peter, I was struggling with something similar to this earlier today. You need to include a "panel =" into your xyplot function. Look at the first few examples here... http://terra.acs.unt.edu/Rdoc/library/lattice/demo/lattice.R I think that you need to do something like... xyplot(yhat~time |Subject,data=datafi,type="l", panel=function(x){ panel.abline(0,1) }) I am not sure exactly what you need to put for function(x)... but I hope this puts you on the right track. Cheers. geoff
