Extract gls Object Data

DESCRIPTION:

If present in the calling sequence used to produce object, the data frame used to fit the model is obtained.

USAGE:

getData(object) 

REQUIRED ARGUMENTS:

object
an object inheriting from class gls, representing a generalized least squares fitted linear model.

VALUE:

if a data argument is present in the calling sequence that produced object, the corresponding data frame (with na.action and subset applied to it, if also present in the call that produced object) is returned; else, NULL is returned.

EXAMPLES:

fm1 <- gls(follicles ~ sin(2*pi*Time) + cos(2*pi*Time), data = Ovary, 
           correlation = corAR1(form = ~ 1 | Mare)) 
getData(fm1)
