gg_scatter: Scatter plot with color directed by PCA

In ygeunkim/goodgraphic: Private tools for ggplot2

Description

Draw a scatter plot and color the points along the principal components. Color direction becomes the data spread the most.

Usage

gg_scatter(data, mapping = aes(), col_low = "#0091ff",
  col_high = "#f0650e", alpha_focus = FALSE, alpha_range = c(0.05,
  0.25), alpha = 1, global = TRUE, ...)

Arguments

data	data frame to be plotted.
mapping	aesthetic mapping. Since this function automatically colors the points, just specify only x and y.
col_low	low end of the gradient.
col_high	high end of the gradient.
alpha_focus	If TRUE; transparency let dense points visible
alpha_range	range argument of [scale_alpha]
alpha	Set alpha parameter at one value
global	give aes mapping in the global ggplot environment.
...	Additional parameters for geom_point()

Examples

gg_scatter(ggplot2::mpg, mapping = ggplot2::aes(x = displ, y = hwy), global = TRUE)
