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	The linkage to be used in the hierarchical clustering. See the 'method' argument in hclust.

Value

Returns a data frame with grouped peaks.
