%description
A set of functions which use the Expectation Maximisation (EM) algorithm

incomplete data via the EM algorithm, Journal of the Royal Statistical
Society, 39(1), 1--22) to take a finite mixture model approach to
clustering. The package is designed to cluster multivariate data that have
categorical and continuous variables and that possibly contain missing
values. The method is described in Hunt, L. and Jorgensen, M. (1999)
