S4 classes to represent log-ratio data transformations.
numericvector to store the absolute row sums (before the closure of the compositions).
charactervector to store the laboratory codes (unique identifiers).
charactervector to store the sample identifiers (allows duplicates in case of repeated measurements).
charactervector to store the group names (if any).
charactervector to store the part names.
charactervector to store the ratio names.
integervector to store the original ordering of the columns.
numericmatrix to store the basis of the transformation.
numericvector to store the weights assigned to the respective log-ratios.
