sampleDistSpectra


An object of S3 class <code><a rd-options="" href="/link/Spectra?package=ChemoSpec&version=4.3.34" data-mini-rdoc="ChemoSpec::Spectra">Spectra</a></code>.


spectra


Character.  A string giving the distance method.  See <code><a rd-options="" href="/link/rowDist?package=ChemoSpec&version=4.3.34" data-mini-rdoc="ChemoSpec::rowDist">rowDist</a></code> for options.


method

plot


Arguments to be passed to the plotting function.



Compute the Distance between samples in a Spectra object.  This is a means to quantify the similarity between samples.  A heat map style plot is an option.


 hplot

A collection of functions for top-down exploratory data analysis of spectral data obtained via nuclear magnetic resonance (NMR), infrared (IR) or Raman spectroscopy.  Includes functions for plotting and inspecting spectra, peak alignment, hierarchical cluster analysis (HCA), principal components analysis (PCA) and model-based clustering. Robust methods appropriate for this type of high-dimensional data are available.  ChemoSpec is designed with metabolomics data sets in mind, where the samples fall into groups such as treatment and control.  Graphical output is formatted consistently for publication quality plots.  ChemoSpec is intended to be very user friendly and help you get usable results quickly.  A vignette covering typical operations is available.
