This paper presents the R package anacor for the computation of simple and canonical correspondence analysis with missing values. The canonical correspondence analysis is speci ed 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 ...Canonical Correspondence Analysis (CCA) Approach. CCA (aka Constrained Correspondence Analysis) is a direct gradient analysis method. It was developed and popularized by ter Braak (1986, 1987). Like CA, it maximizes the correlation between species and sample scores.
