R help - Jul 2011 - How do I get two levels of grouping for in a lattice panel function?

Dear list,

I'm working on a panel function where I would like to be able to visualise
data grouped by the category of the data, and then also changes in summary
descriptives from one condition to another in the same scatter plot. Like
the figure attached, but with one polygon for each subset of the data set
given by a second variable (with colours still coming from the variable
specified in the "groups" argument).


Any ideas?

/Fredrik

To paraphrase your sig:

into them, you don't get anything out of it."
