Other packages exist which can be used to perform selections,
transform values, and generally analyse and categorise the
PISAFIND parameterisations.
With sufficient effort they may be used to classify objects.
Catalogue manipulations can be done using the CURSA
[5] and CATPAC[8] packages.
More general plotting packages also be used to investigate the various
results; PONGO [12] and SM [13]
both plot data points and allow mathematical transformations of
columns.
Using CLUSTAN you could investigate the natural clustering of objects
in parameter space (with the aim of classification in mind).
