Purpose

After the package concor was removed from the CRAN repository on 2021-02-15 as check problems were not corrected in time, there was no way to run the CONCOR algorithm for regular equivalence. The maintainer could not be contacted. Thus, the other available package concorR implements the alforithm only for strctural equivalence.

This package corrects the errors in the abandoned package concor and rewrites the entire documentation using the latest version of Roxygen.

Original description

The four functions svdcp (cp for column partitioned), svdbip or svdbip2 (bip for bi-partitioned), and svdbips (s for a simultaneous optimization of one set of r solutions), correspond to a “SVD by blocks” notion, by supposing each block depending on relative subspaces, rather than on two whole spaces as usual SVD does. The other functions, based on this notion, are relative to two column partitioned data matrices x and y defining two sets of subsets xi and yj of variables and amount to estimate a link between xi and yj for the pair (xi, yj) relatively to the links associated to all the other pairs.
