labelExtremes3d

A matrix of 3 columns containing x, y and z values for the labels, with rows corresponding to sample names.

data

A character vector of sample names; must have length equal to <code>nrow(data)</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 x, y an

A utility function to identify the extreme values in a 3D plot data set, presumably so that they can be labeled.  Algorithm is similar to <code><a href="/link/labelExtremes?package=ChemoSpec&version=3.0-1" rd-options="" data-mini-rdoc="ChemoSpec::labelExtremes">labelExtremes</a></code>, except that <code>labelExtremes3d</code> does not do the plotting (because the results are used by functions that use different plotting paradigms).

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.
