Description

Arrow for PCA bi-plot

Usage

geom_arrow_pca(
  pca_recipe,
  x = PC1,
  y = PC2,
  x_origin = 0,

x_origin	(numeric) x-origin of the arrow
y_origin	(numeric) y-origin of the arrow
length	length of the arrow defined by function ggplot2::unit (passed to ggplot2::arrow)
type	type of the arrow head (passed to ggplot2::arrow)
color	color of the arrow segment (passed to ggplot2::geom_segment)
...	passed to geom_segment

Value

plot arrow
