...bar represents auth.sum==-8 where datecat==1, then immediately next to it is auth.sum==-8 where datecat==2, then a small amount of space, then the -7 bars, etc. (I may not be doing the best job describing this, but it's a commonly-seen graph type; see http://www.parentingbookmark.com/media/bar%20graph.jpg for an example [thanks to images.google.com for finding it]). The closest I've come is to use: barplot(table(hcd.df$auth.valence, hcd.df$datecat), beside=TRUE) which plots the two *distributions* side by side (all the datecat==1 then all the datecat==2). Any advice? Thanks. -----------...
