Hi all, I wish to use rp.tkrplot from the rpanel package with subplots produced by layout or split.screen. My problem is that I want to use a click function, but I can't work out how to convert the x and y values it produces into the values on the plots as unlike for a single plot they don't match. For example in the following code the (0,0) and (1,1) corners of the bottom left plot are given as approx (-.1,-.05) and (.23,.45). Thanks for any help, Philip Wilson library(rpanel) panel<-rp.control() plots<-function(panel) { par(mar=rep(1.5,4)) layout(rbind(1:3,4:6)) for (i in 1:6) plot(0:4*.25,runif(5),xlim=0:1,ylim=0:1) } click<-function(panel,x,y) {print(c(x,y)); panel} rp.tkrplot(panel,plot1,plots,click,hscale=1.8,vscale=1.8)
