CHR.object {DTR} R Documentation

## Cumulative hazard ratio object

### Description

This class of objects is returned by the CHR class of functions to represent a list of cumulative hazard ratio estimates and estimated standard errors for dynamic treatment regimes (DTRs). Objects of this class have methods for the functions print, summary, and plot.

### Arguments
