PartitionData: Assign data points to a set of nodes

In Albluca/ElPiGraph.R: Elastic principal graph construction

Description

Assign data points to a set of nodes

Usage

PartitionData(X, NodePositions, SquaredX = NULL, TrimmingRadius = Inf,
  nCores = 1)

Arguments

X	an n-by-m numeric matrix with the coordinates of the data points
NodePositions	an k-by-m numeric matrix with the coordiante of the nodes
SquaredX	the sum by row of the squared positions rowSums(X^2). If NULL it will be calculated by the fucntion.
TrimmingRadius	Maximum distance of data points to the nodes to assign a point to a node
nCores	number of cores to use.

Value

A list containing two components: Partition (containing the associated nodes) and Dists (containing the squqred distance from the node)
