[R] plot question

[Catherine Carter]

Hi everyone,

I have what may appear to be a newbie question, but I have looked 
everywhere I can think to look and I cannot find an answer. On page 35 
of "An Introduction to R" the following command appears: 
plot(ecdf(eruptions), do.points=FALSE, verticals=TRUE). What is the 
do.points argument? I know what it does (suppresses printing of the 
points) but where can I find help on it? I want to be able to explain it 
fully to my students.

Thanks for your help,
Cathy
