binSpectra

This function will bin a <code>Spectra</code> object by averaging every
<code>bin.ratio</code> frequency values, and summing the corresponding intensity
values. The net effect is a smoothed and smaller data set. If there are
gaps in the frequency axis, each data chunk is processed separately. Note:
some folks refer to binning as bucketing.

A collection of functions for top-down exploratory data analysis
of spectral data including nuclear magnetic resonance (NMR), infrared (IR),
Raman, X-ray fluorescence (XRF) and other similar types of 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 for structured
experiments, such as metabolomics investigations, where the samples fall into
treatment and control groups. Graphical output is formatted consistently for
publication quality plots. ChemoSpec is intended to be very user friendly and
to help you get usable results quickly. A vignette covering typical operations
is available.
