Generalized Least Squares Estimates

Obtain estimates using generalized least squares (gls).

gls(formula, data, vc = NULL, test=c("none","F"))

`formula`	An object of class "formula": a symbolic description of the model to be fitted.
`data`	An data frame containing the variables in the model.
`vc`	An object from `estVC` or `aicVC` or an estimated variance-covariance matrix induced by relatedness and environment if not NULL.
`test`	Wheter F-test is performed.

A matrix with columns: "Estimate", "Std. Error", "t value" and "Pr(>|t|)", or an ANOVA table if F-test is requested.
