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. By default 0, which is useful for many use cases. However, if the data has only positive (or only negative) values, it may be worthwhile to specify this. Use NA to set it to the middle of the value range.

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
  ggplot(diam_exp, aes(x = carat, y = price, color = cut)) +
    geom_point(size = 2) +
    scale_color_discrete_c4a_seq("hcl.blues2") +
    theme_light()

  # continuous sequential scale
  ggplot(diam_exp, aes(x = carat, y = price, color = depth)) +
    geom_point(size = 2) +
    scale_color_continuous_c4a_seq("hcl.blues2", range = c(0.4, 1)) +
    theme_light()

  # continuous diverging scale
  ggplot(diam_exp, aes(x = carat, y = depth, color = price)) +
    geom_point(size = 2) +
    scale_color_continuous_c4a_div("wes.zissou1", mid = NA) +
    theme_light()

  # binned sequential scale
  ggplot(diam_exp, aes(x = carat, y = price, color = depth)) +
    geom_point(size = 2) +
    scale_color_binned_c4a_seq("scico.batlow", range = c(0.4, 1)) +
