Hi, I am use to matlab and when I want to overlay multiple plots on the same graphics devise I type in "hold on" and when I am done I type in "hold off" Does R have an equivalent feature? can someone give me an example where they plotted 2 functions on top of each other? thanks
Start the plot using "plot", add lines and points using "lines" and "points", as described in the examples with "?plot". hope this helps. spencer graves christoff pale wrote:>Hi, >I am use to matlab and when I want to >overlay multiple plots on the same graphics devise >I type in "hold on" and when I am done I type in >"hold off" > >Does R have an equivalent feature? >can someone give me an example where they plotted >2 functions on top of each other? thanks > >______________________________________________ >R-help at stat.math.ethz.ch mailing list >https://www.stat.math.ethz.ch/mailman/listinfo/r-help > >
