  pc_x = 1, pc_y = 2, point_size = 2.16, point_alpha = 0.9,
  base_size = 11, base_family = "", legend_position = "right",
  palette = NULL, ...)

Arguments

data: A `ggpop_pca` object.
title, subtitle, caption: Plot text.
pc_x, pc_y: Principal components to plot.
point_size, point_alpha: Point appearance.
base_size, base_family, legend_position: Publication theme settings.
