I'm not familiar with Matlab, but from what I know, "hold on" is used to overlay more stuff on the existing plot. In R such things are accomplished a bit differently: One put up a plot, then use things like lines(), points(), abline(), etc. to add to the existing plot. The closest thing to "hold on" in Matlab, I think, is par(new=TRUE).
