[R] Compact letter display for interaction effects

[Josh Caplan]

Hello,

I am interested in generating a compact letter display for the results 
of Tukey HSD tests that contain interaction effects. The 'cld' method in 
the 'multcomp' package seems only to work for main effects. Does such a 
thing exist already? Thank you for any thoughts,

Josh
