Dear List, I am trying to plot several separate polygons on a graph. I have figured out how to do it by manually, but have too much data to use such a tedious method. I would appreciate your help. I have made a simple example to illustrate the problem. How can I get x into the proper format (x1)? #Sample data x<-c(1,2,3,4,5,6) y<-c(1,2,2,1) #I need to format the data like this x1<-c(1,1,2,2,NA,3,3,4,4,NA,5,5,6,6,NA) y1<-rep(c(1,2,2,1,NA),length(x)/2) #Final plot plot(c(1,6), 1:2, type="n") polygon(x1,y1,density=c(40)) Thanks, Tim Tim Clark Department of Zoology University of Hawaii

Nice, Uwe. Small correction: make that nrow=4: x1 <- as.numeric(rbind(matrix(rep(x, each=2), nrow=4), NA)) -Peter Ehlers Uwe Ligges wrote:> > > On 11.02.2010 22:38, Tim Clark wrote: >> Dear List, >> >> I am trying to plot several separate polygons on a graph.

Thanks Uwe! And Peter for the correction. I would never have come up with that!
