[R] Manova in R vs. SAS

[Bill Kristan]

While I was helping a SAS-using friend with an analysis I noticed some 
differences in the multivariate test statistics, approximate F statistics, 
and p-values in the manova function using R and proc GLM using SAS. The 
univariate coefficients are identical. Is there a reason to expect R and SAS 
to give different results?

Thanks,

Bill Kristan.
