anacor-0.9.0 is on CRAN (by De Leeuw and Mair)
anacor does correspondence analysis and canonical correspondence
analysis. It can make row plots, column plots,
joint plots, Benz?cri plots, regression plots,
and transformation plots. Where appropriate, plots can
be in 3d using either rgl or scatterplot3d. Row and
column points can be in standard scaling, Benz?cri
scaling, Goodman scaling, row-centroid, or column-centroid
scaling.
The summary method writes out a table with the chi-square
(inertia) decomposition, it also writes out the singular
values, and their asymptotic standard errors under multinomial
sampling. Plots of the category quantifications (row scores
and column scores) can be made optionally with asymptotic
confidence ellipses, again based on multinomial sampling.
The package contain various utilities to switch data formats,
in particular to transform data frames to Burt matrices,
to indicator matrices, and even to fuzzy indicator matrices
using B-spline bases.
The vignette for the package (not added yet) is a paper
also submitted to the special psychoR issue of JSS. You
can get a preprint at
http://idisk.mac.com/jdeleeuw-Public/psychoR/anacor.zip
The psychoR directory also has the anacor package, the
homals package, and the homals paper. smacof (many forms
of multidimensional scaling) is next.
