This package furnishes R with a suite of object-oriented data structures: stack, queue, deque, max-heap, min-heap, binary search tree, and splay tree.

Model-Based Clustering and Classification with the Multivariate
Contaminated Normal Distribution

(with eigen-decomposed scale matrices) via the expectation conditional-
maximization algorithm under a clustering or classification paradigm.

Create Contour Plots from Data or a Function
person("Collin", "Erickson",
email = "collinberickson@gmail.com",
role = c("aut", "cre"))
Provides functions for making contour plots.
The contour plot can be created from grid data, a function,
or a data set. If non-grid data is given, then a Gaussian
process is fit to the data and used to create the contour plot.
