[R] Adding data to existing plot with new=TRUE does not appear to	work 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).  From ?par I learned that I can/should set new=TRUE in either par() or the plot function itself. However with the following reduced code, I get only a plot with a column of data points with x==2. 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) plot(aa,bb, xlim=range(0,3), ylim=range(0,10), new=TRUE) Also, when I insert a op <- par(new=TRUE) either before or immediately after the first plot statement (the type='n' one) in the above code fragment, the resulting graph still only shows one column of data. Have I misinterpreted the instructions or the functionality of new=TRUE?
