## Create a matrix of all binary combinations

### 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.
