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 On Mon, Sep 13, 2010 at 5:00 PM, David Winsemius <dwinsem...@comcast.net>wrote: > > On Sep 13, 2010, at 5:48 PM, Kevin Burnham wrote: > > Hi All, >> I am trying to plot per cent correct scores (column name =PerCorr) for >> each >> of about 40 subjects.
