mclustSpectra: mclust Analysis of a Spectra Object PCA Results

Description

This function is a wrapper for the Mclust function and associated plotting functions.

Usage

mclustSpectra(spectra, pca, pcs = c(1:3), dims = c(1, 2),
	plot = c("BIC", "proj", "error"), use.sym = FALSE, ...)

Value

The Mclust model is returned invisibly, and a plot is made.

Examples

data(CuticleIR)
class <- classPCA(CuticleIR)
mclustSpectra(CuticleIR, class, main = "Cuticle IR", plot = "BIC")
mclustSpectra(CuticleIR, class, main = "Cuticle IR", plot = "proj")
mclustSpectra(CuticleIR, class, main = "Cuticle IR", plot = "error",
	truth = CuticleIR$groups)
