[R] Compact letter display for interaction effects

       This opened a table for me in a web browser identifying 3 help 
pages in 'multcomp' and 1 in 'multcompView' that mention 'compact letter 
display'.  Functions in multcompView will work anything that looks like 
a distance or similarity matrix.  You need to decide what to use so the 
results make sense.


       Hope this helps.
