xsimplex {combinat} | R Documentation

## Generates all points on a (p,n) simplex lattice (i.e. a p-part composition of n).

### Description

Generates all points on a p,n simplex lattice (i.e. a p-part composition of n). Each point is represented as x, a p-dimensional vector of nonnegative integers that sum to n. If argument "fun" is not null, applies a function given by the argument to each point. If simplify is FALSE, returns a list; else returns a vector or an array. "..." are passed unchanged to function given by argument fun, if any.

### Usage

    xsimplex(p, n, fun=NULL, simplify=TRUE, ...)

### Arguments

`p` | first parameter of lattice description
`n` | second parameter of lattice description
`fun` | function to be applied pointwise
`simplify` | logical: if FALSE, value is a list, otherwise a vector or array
`...` | parameters to be passed to `fun`

### Examples

    #Compute Multinomial(n = 4, pi = rep(1/3, 3)) p.f.:
       xsimplex(3, 4, dmnom, prob=1/3)
