R help - Sep 2010 - Plot with Group # as pch

Hi All,
I am trying to plot per cent correct scores (column name =PerCorr) for each
of about 40 subjects.  I would like the character representing each score to
be a number between 0 and 4 depending on the subject's group (from the
column Subject.Group).
Also, I would ideally be able to order the data by Subject.Group first so
that all of group 0 is to the far left of the graph and all of group 4 to
the far right.
Thanks,
Kevin

You can use text(x,y,   labels=    ) for the plotting ... once you  
have a working example that is.
