In speaq2: Wavelet Based Tools for Feature-Wise Analysis and Quantification of Nuclear Magnetic Resonance (NMR) Spectra

Description

Internal function in the PeakAligner 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 aligned.
min.samp.grp	The minimal amount of samples needed te form a group.
max.dupli.prop	The maximal duplication proportion allowed for a group to be considered a sigle 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 realigned peaks (aligned on groupIndex).
