       mix.2rplus(X)
       mix.2rmult(X)

### Arguments

`X` | mixture object to be converted

### Details

A 'compositions' object is obtained from the mixtute object m, having the same data matrix as mixture object m i.e. m$mat.

    ap <- mix.2aplus(m)   # ap is a 'compositions' object of the aplus class
    ac <- mix.2acomp(m)   # ac is a 'compositions' object of the acomp class
