sampleDistSpectra: Compute the Distance Between Samples in a Spectra Object

Description

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.

Usage

sampleDistSpectra(spectra, method = "pearson", plot = TRUE, ...)

Value

A numeric matrix giving the correlation coefficients.

The sample distances can be used to cluster the samples. See for example hcaSpectra.

Examples

require("lattice")
data(metMUD2)
sampleDistSpectra(metMUD2, main = "Sample Correlations for metMUD2")
