plotScoresG: Plot PCA Scores of a Spectra Object using GGobi

Description

Plots the specified PCs from a PCA analysis of a "Spectra" object using GGobi.

Usage

plotScoresG(spectra, pca, pcs = c(1:3), scheme = "primary")

Value

None. Side effect is a plot in an X11 window created by GGobi. The mapping of colors from the Spectra object to the GGobi color schemes is printed at the console, since the original color choices may not be acceptable to GGobi.
