[R] Looking for parallel functionality between Matlab and R

[Greg Snow]

For a), if you really want the plots overlayed, it is best to use
something like matplot, or use the points or lines function to add the
later plots to the first.  You can also get the overlay effect using
par(new=TRUE), but then you need to be careful with axis labels and
scales and the plot may end up being more confusing then helpful.

For b), if you are just doing a quick exploration of the plot, there is
the zoomplot function in the TeachingDemos package that may work for
you.  If you want a plot to print/save, it is best to specify xlim and
ylim in the initial plotting function to create it at the correct
size/zoom from the beginning.

Hope this helps,
