setPartitions: Generate set partitions

In senhu/FCBMA: Factor collapsing with Bayesian model averaging for regression models

Description

Enumeration of set partitions given the number of elements in a set

Usage

setPartitions(num)

setPartitions_restricted(num, group = NULL, apart = NULL)

Arguments

num	the number of elements in a set
group	a vector indicating which elements should be grouped together
apart	a vector indicating which elements should not be grouped together

Value

a matrix of all set partitions

Note

This function is based on the setparts function from "partitions" package (R. K. S. Hankin) with modifications for FCBMA problem.
