Convert an object of class matrix, data.fram or acomp to an object of class compositional

1	as.compositional(x, method = NULL, colmap = "rainbow")

`x`	an object of class `matrix`, `data.fram` or `acomp`
`method`	dissimilarity measure, either 'aitchison' for Aitchison's CLR-distance or 'bray' for the Bray-Curtis distance.
`colmap`	the colour map to be used in pie charts.

PT.acomp <- as.acomp(Namib$PT)
PT.compositional <- as.compositional(PT.acomp)
print(Namib$PT$x - PT.compositional$x)
