The scagnostics package implements the graph theoretic scagnostics
described by Leland Wilkinson, Anushka Anand and Robert Grossman
(http://www.ncdm.uic.edu/publications/files/proc-094.pdf), building on
an old idea of Tukey's to define indices of "interestingness" to help
guide the search for interesting features in the pair-wise
scatterplots of a highly multivariate dataset.
The scagnostics package currently only supports two methods, one which
computes the scagnostics for a pair of variables, and the other for
all pairs of variables in a data.frame.
If you are attending the JSM, there is a session on scagnostics.

(The package has just been added to CRAN, it may be a couple of days
before it is available on your local mirror)
