[R] graphing with barchart question

[Matthew Bridgman]

Sorry.
I have attached my data frame: DV = dv; IV = bins; subject = id,  
Group = group.
barchart(dv ~ bins | id + group, groups = group, data = matt.df)

The two suggestions you offered give me error messages regarding  
invalid line type and do not plot all of the data. If I drop the  
'groups' argument I get all of the data, but it plots all  
combinations of group and id (yielding 36 plots instead of 18). Is  
there a way to eliminate some of the combinations?

Thanks again for your help.

Matt
