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?

If you are not doing what you truly enjoy its your obligation to
yourself to change.
