[R] similar limma's contrasts.fit() for lme (mixed effect model) object
Dear R help, In limma package, contrasts.fit() function is very useful. I am wondering whether there is a similar function for lme object, which means given a mixed linear model fit, compute estimated coefficients and standard errors for a given set of contrasts. Thanks, Shirley

Shirley,
The contrast package can do this. The method of specifying the contrast
conditions/coefficients is different (and I think easier).
