The S4-version of the data container "rplus" for compositional data. More information in 
<code>rplus</code>

classes

Provides functions for the consistent analysis of compositional
data (e.g. portions of substances) and positive numbers (e.g. concentrations)
in the way proposed by J. Aitchison and V. Pawlowsky-Glahn.

Compositional Data Analysis

rplus-class function

A virtual Class: No objects may be directly created from it. 
This is provided to ensure that rplus objects behave as data.frame or structure under certain circumstances. Use <code>rplus</code> to create these objects.
