object
|
an object inheriting from class glsStruct ,
representing a list of linear model components, such as
corStruct and varFunc objects.
|
data
|
a data frame in which to evaluate the variables defined in
formula(object) .
|
control
|
an optional list with control parameters for the
initialization and optimization algorithms used in
gls . Defaults to list(singular.ok = FALSE, qrTol =
.Machine$single.eps) , implying that linear dependencies are not
allowed in the model and that the tolerance for detecting linear
dependencies among the columns of the regression matrix is
.Machine$single.eps .
