anacor-package: Simple and Canonical Correspondence Analysis

Description

This package performs simple and canonical CA on a two-way frequency table (with missings) by means of SVD. Different scaling methods (standard, centroid, Benzecri, Goodman) as well as various plots including confidence ellipsoids are provided.

Details

ll{ Package: anacor Type: Package Version: 1.0-4 Date: 2013-11-30 License: GPL } The main function of the package is anacor() which performs simple CA. The input dataset tab is a (incomplete) frequency table. Various scaling options in terms of standard, centroid, Benzecri, and Goodman scaling are provided. They can be specified using the scaling argument. If covariates for row/column scores are provided, canonical CA will be computed. Utility functions to create various types of indicator matrices are implemented.
