class RClustergeneration(RPackage):
    """Random Cluster Generation (with Specified Degree of Separation).

    We developed the clusterGeneration package to provide functions  for
    generating random clusters, generating random  covariance/correlation
    matrices, calculating a separation index (data and population version) for
    pairs of clusters or cluster distributions, and 1-D and 2-D projection
    plots to visualize clusters.  The package also contains a function to
    generate random clusters based on factorial designs with factors such as
    degree of separation, number of clusters, number of variables, number of
    noisy variables."""
