grindr layers for multivariate plots

Arguments

x: a list, typically returned by plot_PCA
center_origin: logical whether to center the origin (default TRUE)
zoom: numeric to change the zoom (default 0.9)
col: color (hexadecimal) to use for drawing components
lwd: linewidth for drawing components
...: additional options to feed core functions for each layer
cex: to use for drawing components
lty: linetype for drawing components
grid: numeric number of grid to draw
border: color (hexadecimal) to use to draw border
pch: to use for drawing components
transp: transparency to use (min: 0 defaut:0 max:1)
conf: numeric between 0 and 1 for confidence ellipses
alpha: numeric between 0 and 1 for the transparency of components
levels_density: numeric number of levels to use to feed MASS::kde2d
levels_contour: numeric number of levels to use to feed graphics::contour
n: numeric number of grid points to feed MASS::kde2d
density: logical whether to draw density estimate
contour: logical whether to draw contour lines
font: to feed text
abbreviate: logical whether to abbreviate names
rect: logical whether to draw a rectangle below names
size: numeric as a fraction of graphical window (default: 1/200)
freq: logicalto feed[hist] (default:FALSE`)
breaks: to feed hist (default: calculated on the pooled values)
split: logical whether to split the two distributions into two plots
bw: to feed density (default: stats::bw.nrd0)
rug: logical whether to add rug (default: TRUE)
title: to add to the plot (default "")
name: to use on axes (default "Axis")
nb_max: numeric number of eigen values to display (default 5)
probs: numeric sequence to feed stats::quantile and to indicate where to draw ticks and legend labels
