Simple and Canonical Correspondence Analysis Using theRPackageanacor

This paper presents the R package anacor for the computation of simple and canonical correspondence analysis with missing values. The canonical correspondence analysis is specied in a rather general way by imposing covariates on the rows and/or the columns of the two-dimensional frequency table. The package allows for scaling methods such as standard, Benz ecri, centroid, and Goodman scaling. In addition, along with well-known two- and three-dimensional joint plots including condence ellipsoids, it oers alternative plotting possibilities in terms of transformation plots, Benz ecri plots, and regression plots.
