S4 classes to represent log-ratio data transformations.
totalsA numeric vector to store the absolute row sums (before
the closure of the compositions).
groupsA factor vector to store the group names.
partsA character vector to store the original part names.
ratioA character vector to store the ratio names.
orderAn integer vector to store the original ordering of the
columns.
baseA numeric matrix to store the basis of the transformation.
weightsA numeric vector to store the weights assigned to the
respective log-ratios.
In the code snippets below, x is a LogRatio object.
