homals-0.9.0 is on CRAN -- by Jan de Leeuw and Patrick Mair
This package implements the methods discussed in Gifi, Nonlinear
Multivariate
Analysis, Wiley, 1990. In the Gifi terminology it covers homals,
princals,
canals, morals, criminals, and overals. The R implementation fills
several
gaps in Gifi, adding multiple ordinal, numerical, and polynomial data
transformations. Differences with previous CRAN version:
a. More R-like with S3 classes, namespace, print, plot, plot3d,
summary, predict methods
b. (Much) better documented functions and data sets
c. Dynamic three-d plot using rgl
d. Static three-d plot using scatterplot3d
e. Predict method that counts "correct" classifications
f. Many bugs fixed
A paper describing the technique and implementation, with many examples,
is almost ready. There is a preprint at http://gifi.stat.ucla.edu/homalsR.pdf
