The line I have now is this:

plot(alldata$haa_Haa, pch=alldata$Subject.Group)

This more or less gives me what I want, but instead of using the actual
group number as the plotting point it converts it to the pch character
corresponding to that number.  Is there a way that the above line could be
modified so that it would use the group 3 itself, rather than the
corresponding charecter?

thanks again,
k
