model.frame.egf: Extract Model Frames

In davidearn/epigrowthfit: Nonlinear Mixed Effects Models of Epidemic Growth

Extract Model Frames

Description

Extracts from a model object any of several data frames used to specify the model, including the mixed effects model frames.

Usage

## S3 method for class 'egf'
model.frame(formula,
            which = c("ts", "windows", "parameters", "extra", "combined"),
            top = egf_top(formula), full = FALSE, ...)

Arguments

formula	an egf object.
which	a character string controlling what is returned: "ts" disease incidence time series. "windows" fitting window endpoints. "parameters" the mixed effects model frame corresponding to top. "extra" variables preserved in formula due to setting of egf argument select_windows. "combined" the result of concatenating (in the sense of cbind) all mixed effects model frames and the data frame corresponding to "extra", then deleting any duplicated variables.
top	a character string specifying a top level nonlinear model parameter, for which = "parameters".
full	a logical, for which = "ts". If TRUE, then complete time series are returned. Otherwise, only observations belonging to fitting windows are returned.
...	unused optional arguments.

Value

A data frame.
