Update a modelStruct Object
DESCRIPTION:
This method function updates each element of
object, allowing
the access to
data.
USAGE:
update(object, data)
REQUIRED ARGUMENTS:
- object
-
an object inheriting from class
modelStruct,
representing a list of model components, such as
corStruct and
varFunc objects.
- data
-
a data frame in which to evaluate the variables needed for
updating the elements of
object.
VALUE:
an object similar to
object (same class, length, and names),
but with updated elements.
NOTE: This method function is primarily used within model fitting
functions, such as
lme and
gls, that allow model
components such as variance functions.
