Description

Create a matrix of all binary combinations for use with the hyperdirichlet distribution

Usage

binmat(n, alternatives = NULL, pnames=NULL)

Arguments

n

Number of binary digits

alternatives

The alternatives; prototypically TRUE and FALSE, but default NULL, taken to mean 0 and 1, is easier on the eye

pnames

Optional vector specifying the column names; default of NULL means to use p1,p2 etc

Value

Function binmat(n) returns an integer matrix of zeros and ones with \(2^n\) rows and \(n\) columns. In binary, the rows count from \(0\) to \(2^n-1\).
