For circles look at the symbols function. For ellipses see the ellipse package
and the my.symbols function in the TeachingDemos package.

Subject: [R] Adding circles or ellipses to graphs
Hello,
I'm developing an ordination using metaMDS (package vegan). The analysis
identifies 3 distinct groups that I'd like to define by either adding
circles or ellipses to help identify the groups. The data set is a
spatial temporal data base depicting change in each of 4 areas over 3
time periods.
I can add lines that would link each of the time - x - area
trajectories, but I'd like to add a circle or an ellipse to these as
well.
Does anyone have any suggestions?
