Thanks for the suggestion. That’s a very interesting and clever way of
displaying both means and differences. It’s not what I was looking for,
though, as it doesn’t display the actual data.
For the record, here’s the syntax for using MMC on the dataset mentioned
in my original posting:
l.mmc=mmc(l, linfct = mcp(trt = "Tukey"))
plot(l.mmc)
(It looks best on data where the group means aren’t very close;
otherwise the labels might overlap.)
