ChemoSpec: Exploratory Chemometrics for Spectroscopy

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.
