Plot aovPCAscores Loadings of a Spectra Object
Uses the results from aovPCAscores to plot the corresponding
loadings.
aovPCAloadings(spectra, LM, pca, plot = 1, loads = 1, ref = 1, ...)
spectra |
An object of S3 class |
LM |
List of matrices created by |
pca |
PCA output from |
plot |
An integer specifying the desired plot. |
loads |
An integer vector giving the loadings to plot. More than 3 loadings creates a useless plot using the default graphics window. |
ref |
An integer specifying the reference spectrum to plot, which appears at the bottom of the plot. |
... |
Additional parameters to be passed to plotting functions. |
None. Side effect is a plot.
