labelExtremes

A matrix containing the x values of the points/samples in the first column, and the y values in the second.

data

A character vector of sample names.  Length must match the number of rows in <code>x</code>.

names

A number describing the fraction of points to be labeled.  <code>tol = 1.0</code> labels all the points; <code>tol = 0.05</code> labels <em>approximately</em> the most extreme 5 percent.  Note that this is simply based upon quantiles, assumes that both x 

A utility function which plots the sample names next to the sample points.  The number of samples labeled can be specified by passing it from the calling function.  Never called by the user. Uses base graphics.

utilities

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.
