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

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.
