Create nested data frame from data with time-dependent covariates

Description

Provides methods to nest data with time-dependent covariates (TDCs). A formula must be provided where the right hand side (RHS) contains the structure of the TDCs

Usage

nest_tdc(data, formula, ...)

## Default S3 method:
nest_tdc(data, formula, ...)

## S3 method for class 'list'
nest_tdc(data, formula, ...)

Arguments

data	A suitable data structure (e.g. unnested data frame with concurrent TDCs or a list where each element is a data frame, potentially containing TDCs as specified in the RHS of formula). Only TDCs present in formula will be returned.
formula	A two sided formula with a two part RHS, where the second part indicates the structure of the TDC structure.
...	Further arguments passed to methods.
vars	A character vector of TDCs that will be nested.
id	A character giving the name of the ID column.
