\description{
General approach to orthonormal coordinates for compositional tables
}
\details{
A contingency or propability table is by definition a compositional data set. This approach consider
the related special properties of compositional tables. It constructs orthonomal coordinates for compositional tables using
the isometric log-ratio approach for given sequential binary partitions on rows and columns.
