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)
x1 <- as.numeric(rbind(matrix(rep(x, each=2), nrow=2), NA)) Uwe Ligges
#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 ______________________________________________ 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.
