unwrap.CBData {CorrBin}R Documentation

Unwrap a CBData object

Description

unwrap.CBData is a utility function that reformats a CBData object so that each row is one observation (instead of one or more clusters). A new `ID' variable is added to indicate clusters. This form can be useful for setting up the data for a different package.

Usage

unwrap.CBData(cbdata)

Arguments

cbdata a CBData object

Value

A data frame with one row for each cluster element (having a binary outcome) with the following standardized column names

Trt factor, the treatment group
ClusterSize numeric, the cluster size
ID factor, each level representing a different cluster
Resp numeric with 0/1 values, giving the response of the cluster element
