Hello all. I need to graph multiple lines of different lengths on the same graph. When I try to add lines I get an error due to different lengths. The only thing I could find when reading up on it was that 'if the data are inputted separately they must be of the same length'. Could someone please let me know how to input the data together? Thanks for any help, Jordan

Hi Jordan, If you want to plot all your lines at once, you will have to pad the shorter one with NAs. I'm assuming that your missing points are on the ends of the lines. line1<-1:10 line2<-c(2,3,4,2,3,4,rep(NA,4)) line3<-c(NA,4,5,6,7,2,3,4,5,NA) matplot(cbind(line1,line2,line3),type="b") However, if you want to plot your original vectors of values without padding, you can do it like this, by specifying the x values as well: plot(line1) line2<-c(2,3,4,2,3,4) lines(1:6,line2) line3<-c(4,5,6,7,2,3,4,5) lines(2:9,line3) Jim
