## S3 method for class 'polywog'
model.frame(formula, ...)

Arguments

formula

a fitted model of class "polywog" (the argument is named formula for consistency with the generic function model.frame)

A data frame containing the variables used to fit the model, with additional attributes (e.g., "terms") used to construct a model matrix.
