ggplot2 plot method for biplotEZ objects

Usage

gg_biplot(
  x,
  exp.factor = 1.2,
  axis.predictivity = NULL,
  sample.predictivity = NULL,
  xlim = NULL,
  ylim = NULL,
  square = TRUE,
  draw = TRUE,
  legend = NULL,
  ...
)

Arguments

x: an object of class biplot with a method (PCA, CVA, ...) applied.
exp.factor: expansion factor for the plotting region.
axis.predictivity: logical or numeric in (0,1); as in plot.biplot.
sample.predictivity: logical or numeric in (0,1); as in plot.biplot.
xlim, ylim: optional axis limits.
square: logical; pad the narrower data range so the panel is square, mimicking base pty = "s" with asp = 1. Default TRUE.
legend: logical; show the ggplot legend for sample groups (default: shown when there is more than one group). Legends for bags, ellipses and means are controlled by legend.type().
...: reserved.

Value

the biplot object, invisibly carrying the ggplot in $gg, with class gg_biplot prepended so that printing displays the plot.
