## The uniform distribution on the simplex

### Description

Generates random compositions with a uniform distribution on the (rcomp) simplex.

### Usage

    runif.rcomp(n,D)

### Arguments

`n` | number of datasets to be simulated
`D` | number of parts

### Value

a generated random dataset of class `"acomp"` or `"rcomp"` drawn from a uniform distribution on the simplex of D parts.
