hclust.grouping {speaq}

Grouping with hierarchical clustering (used in the PeakGrouper function)

Description

Internal function in the PeakGrouper function for generating the hierarchical clustering tree and cutting it.

Usage

hclust.grouping(
  current.peaks,
  min.samp.grp = 1,
  max.dupli.prop = 0.25,
  maxClust = 10,
  linkage = "average"
)

Arguments

current.peaks

A number of neighbouring peaks to be grouped.

min.samp.grp

The minimal amount of samples needed to form a group.

max.dupli.prop

The maximal duplication proportion allowed for a group to be considered a single group.

maxClust

The maximum number of clusters (depth of the tree).

linkage
