[R] Heeeeeelp! Estimatet Marginal Means of ANOVA needed!

[Liaw, Andy]

I've never used SPSS, so don't know what it refers to as "estimated marginal
means".  However, my guess is that they are probably what SAS calls LS
(least squares) means.  I know Prof. Yandell has written a lsmeans()
function for his "pda" package (supporting his book, "Practical Data
Analysis for Designed Experiments") which you can find on his web page.

Hope this helps,
Andy
