Creates an interactive 3D plot of PCA scores from the analysis of a
Spectra object, color coded according the to scheme stored in
the object. The plot is created by plotly and appears in a browser window.
plot3dScores(
spectra,
pca,
pcs = c(1:3),
ellipse = TRUE,
rob = FALSE,
cl = 0.95,
frac.pts.used = 0.8
)An object of S3 class Spectra().
An object of class prcomp.
A vector of three integers specifying the PCA scores to plot.
Logical indicating if confidence ellipses should be drawn.
Logical; if ellipse = TRUE, indicates that robust
confidence ellipses should be drawn. If FALSE, classical confidence
ellipses are drawn.
A number indicating the confidence interval for the ellipse.
If ellipse = TRUE and rob = TRUE, a
number indicating the fraction of the data points to be considered "good"
and thus used to compute the robust confidence ellipse.
None. Side effect is a plot in a browser window.
