Princomp/Graph

[Eric Imbert <imbert@isem.univ-montp2.fr>]

After a Principal Component Analysis (procedure princom), I would
like to make a 2D-graph using the scores.
To symbolize the data, I would like to use a symbol code refering to the 
group to which the individuals belong (the sex of the individuals for 
instance) in order to see the groups on the 2D-graph.
Does anybody have an idea ?

Eric.
