Biplots of PLSR and PCR Models.
Biplot method for mvr objects.
## S3 method for class 'mvr'
biplot(x, comps = 1:2, which = c("x", "y", "scores", "loadings"),
var.axes = FALSE, xlabs, ylabs, main, ...)x |
an |
comps |
integer vector of length two. The components to plot. |
which |
character. Which matrices to plot. One of |
var.axes |
logical. If |
xlabs |
either a character vector of labels for the first set of
points, or |
ylabs |
either a character vector of labels for the second set of
points, or |
main |
character. Title of plot. If missing, a title is
constructed by |
... |
Further arguments passed on to |
biplot.mvr can also be called through the mvr plot
method by specifying plottype = "biplot".
