Hi,
If you have a variable, that defines what you want to differentiate (sociology,
economics etc.) then you can add color depending on the value of that
variable. You will have to convert it to numeric if it is not.
An example would be
plot( iris[ , 1 ], iris[ , 2], col = iris[ , 3 ] )
I don't know about the maptools package but one general way to do this
would be to compute the convex hull (?chull) of the augmented set of

simple command system(mkdir toto) to create a directory toto, it tells me

Does anybody knows how it works ? Is it a path problem ? Maybe the answer is
simple: I am a R user
