Hi if you change your code
plot(1,10, xlim=range(0,3), ylim=range(0,10), type='n') aa <- rep(1,10) bb <- 1:10 plot(aa,bb, xlim=range(0,3), ylim=range(0,10), new=TRUE) aa <- rep(2,10) par(new=T) plot(aa,bb, xlim=range(0,3), ylim=range(0,10), new=TRUE) you will get both columns plotted. However you can get similar result with using points plot(1,10, xlim=range(0,3), ylim=range(0,10), type='n') aa <- rep(1,10) bb <- 1:10 points(aa,bb) aa <- rep(2,10) points(aa,bb) Regards Petr [EMAIL PROTECTED] [EMAIL PROTECTED] napsal dne 04.07.2007 09:48:15: > Dear all, > > I am trying to shove a number of cmdscale() results into a single plot > (k=1 so I'm trying to get multiple columns in the plot).
