plotEll

Plot 50% and 95% confidence ellipses for mixtures of Gaussians fitted using
 <code>FLXMCmvnorm</code>.

cluster

A general framework for finite mixtures of regression
models using the EM algorithm is implemented. The E-step and all
data handling are provided, while the M-step can be supplied by the
user to easily define new models. Existing drivers implement
mixtures of standard linear models, generalized linear models and
model-based clustering.
