get_cutpoints-methods: get_cutpoints

In TSDT: Treatment-Specific Subgroup Detection Tool

get_cutpoints

Description

Accessor method for cutpoints slot in TSDT objects.

Usage

get_cutpoints(.Object, subgroup, subsub = NULL)

## S4 method for signature 'TSDT_CutpointDistribution'
get_cutpoints(.Object, subgroup = character, subsub = NULL)

## S4 method for signature 'TSDT'
get_cutpoints(.Object, subgroup = character, subsub = NULL)

Arguments

.Object	A TSDT object.
subgroup	The anonymized subgroup.
subsub	A particular component of the subgroup to retrieve.

Details

The summary results from TSDT provide a set of 'anonymized' subgroups in a form similar to 'X1<xxxxx'. The variable X1 may have been selected as a splitting variable in several bootstrapped samples. The exact numerical cutpoint for X1 could vary from one sample to the next. The get_cutpoints method returns all the numerical cutpoints associated with this subgroup. If the subgroup is a compound subgroup defined on more than one spliting variable the user can specify the 'subsub' parameter to get the cutpoints associated with a particular component of the subgroup.

Examples

## Not run: 
example( TSDT )
## You can access the cutpoints slot of a TSDT object directly
ex2@cutpoints

## You can also use the accessor method
get_cutpoints( ex2@cutpoints, subgroup = 'X1<xxxxx' )

## Retrieving a compound subgroup defined on multiple splits
get_cutpoints( ex2, subgroup = 'X1<xxxxx & X1>=xxxxx' )

## Retrieving a single component from the compound subgroup
get_cutpoints( ex2, subgroup = 'X1<xxxxx & X1>=xxxxx', subsub = 'X1>=xxxxx' )

## End(Not run)
