col4all scales for ggplot2

col4all scales for ggplot2. The scale functions are organized as scale_<aesthetic>_<mapping>_c4a_<type>, where the <aesthetic> should be either colo(u)r or fill, <mapping> refers to the mapping that is applied (discrete, continuous or binned), and <type> is the palette type: cat, seq, or div.

Arguments

palette, reverse, order, range

See c4a.

...

parameters passed on to the underlying scale functions: discrete_scale, continuous_scale, and binned_scale.

mid

data value that should be mapped to the mid-point of the diverging color scale

n_interp

number of discrete colors that should be used to interpolate the continuous color scale. Recommended to use an odd number to include the midpoint

Value

A ggplot2 component that defines the scale

Examples

if (require("ggplot2")) {
  data("diamonds")
  diam_exp = diamonds[diamonds$price >= 15000, ]
  diam_exp$clarity[1:500] = NA

  # discrete categorical scale
  ggplot(diam_exp, aes(x = carat, y = price, color = color)) +
    geom_point(size = 2) +
    scale_color_discrete_c4a_cat("carto.safe") +
    theme_light()

  # missing values
  c4a_plot("tol.muted", 8)
  ggplot(diam_exp, aes(x = carat, y = price, fill = clarity)) +
    geom_point(size = 2, shape = 21) +
    scale_fill_discrete_c4a_cat("tol.muted") +
    theme_light()

  # discrete sequential scale

    geom_point(size = 2) +
