R help - Jun 2005 - overlaying plots

surely this not hard, but i can't figure it out.  i'd like to overlay
the results of two ecdf's.  
 
e.g. xx<--ecdf(x) and yy<--ecdf(y).  i'd like to plot xx and yy on the
same graph.   
 
thanks...mj

Please read the chapter on plotting in "An Introduction to R" where
this is
explained.

You can simply do
plot(xx)
plot(yy,add=T)
