R help - Aug 2003 - gls function

Dear all

I use the gls function but in contrast to the lm function in which when I type 
summary(lm(...))$coef I receive all the coefficients (estimate, Std. Error,
t-value and pvalue), with gls when I  type summary(gls(...))$coef  I only
receive the estimate of the reg. coefficient without std. error and t- and
p-values.
Dou you have any suggestion how to solve my problem?

With kind regards
Prodromos Zanis

Look at the structure of the value returned by summary applied to a
gls object.

library(nlme)
example(gls)
str(summary(fm1))

You will find that you want to extract

summary(fm1)$tTable
