[R] ?manova multiple comparisons

[Zachary Holden]

R wizards,

I'm trying to extract multiple comparisons from a MANOVA in R. I've exhausted other resources, and don't want to revert to using SAS for this... 

I'm doing simple MANOVA's in R, with a bivariate response variable (Y) and a treatment with four levels (1,2,3,4) 

model<- manova(Y~TREATMENT, test="Hotelling")

I'm unable to find guidance or code on how I can test for signficant differences between individual levels of my treatment, as you'd do with TukeyHSD in a univariate analysis situation. 

Can anyone help me out? 

Thanks in advance,
Zack
