Description

coming soon.

Usage

nonHierarchicalClustering(clustering, data = NULL, k = NULL, nRepeats = 1, ...)

Arguments

clustering	A vector assigning genes or samples to clusters, or a function
data	The data to be clustered if clustering is a function.
k	The number of clusters to be generated
nRepeats	The number of runs to be averaged.
...	Additional parameters to be passed to clustering

Details

coming soon.

Value
