varFunc: Variance Function Structure
In nlme: Linear and Nonlinear Mixed Effects Models
varFunc R Documentation
Variance Function Structure
Description
If object is a one-sided formula, it is used as the argument to
varFixed and the resulting object is returned. Else, if
object already inherits from class "varFunc",
such as all standard ‘varClasses’,
it is returned unchanged.
Usage
varFunc(object)
Arguments
object
either an one-sided formula specifying a variance
covariate, or an object inheriting from class "varFunc",
representing a variance function structure.
Value
an object from class "varFunc", representing a variance function
structure.
