plotHCA

An object of S3 class <code>"Spectra"</code>.

spectra

A <code><a href="/link/hclust?package=ChemoSpec&version=3.0-1" rd-options="" data-mini-rdoc="ChemoSpec::hclust">hclust</a></code> object.

hclst

sub.title

Logical; if true, the color scheme will be black and lower-case letters will be used to indicate group membership.

use.sym

Additional parameters to be passed to the plotting routines.

This function plots the results of an HCA analysis of a <code>"Spectra"</code> object.  This is not called directly by the user -- <code><a href="/link/hcaSpectra?package=ChemoSpec&version=3.0-1" rd-options="" data-mini-rdoc="ChemoSpec::hcaSpectra">hcaSpectra</a></code> and <code><a href="/link/hcaScores?package=ChemoSpec&version=3.0-1" rd-options="" data-mini-rdoc="ChemoSpec::hcaScores">hcaScores</a></code> use it (see those pages for examples).

multivariate

hplot

cluster

A collection of functions for plotting spectra (NMR, IR etc) and carrying out various forms of top-down exploratory data analysis, such as HCA, PCA and model-based clustering.  The design allows comparison of data from samples which fall into groups such as treatment vs. control.  Robust methods appropriate for this type of high-dimensional data are available.  ChemoSpec is designed to be very user friendly and suitable for people with limited background in R.
