I would like to be able to estimate *confidence* *intervals* for a *linear
combination of coefficients* for a *GLS* model.

I am familiar with the function estimable from the gmodels package. This
function allows to compute and test contrasts for lm, glm, lme, lmer, and
geese objects and *NOT for GLS objects.*

Is there any function equivalent or similar to *estimable* to treat *gls
objects*? I looked for it with no success.

Any help will be appreciated.

Thanks

Maria
