Arguments

...: additional parameters passed to colorify, discrete_scale and/or scale_color_gradientn
aesthetics: string, default: 'color', see discrete_scale and scale_color_gradientn for more aesthetics
discrete: boolean, default = FALSE (calls scale_color_gradientn), else TRUE (calls discrete_scale)
nn: integer, default: Inf, length of gradients, if Inf then set to 256
n: integer, default: 2, amount of colors(/gradients) to return, only works if not discrete
colors: character (vector), combination of selecting palette(s) by name (options: see display_palettes()), and/or vector of R color names and/or color hexcodes
colors_lock: numeric/boolean, default: NULL, numerical or logical index of colors (not) to be modified, if logical length != colors it will be cut or filled with TRUE/FALSE, prefix with '!' for logical vectors and '-' for numerical vectors to get inverse, see examples. If nn %% length(colors) == 0, i.e. if nn divisive by amount of colors without rest, set repeat given locking pattern
hf: hue factor, default: 1, multiply values by factor, proportional to base value of 1
sf: saturation factor, default: 1, multiply values by factor, proportional to base value of 1
lf: lightness/brightness factor, default: 1, multiply values by factor, proportional to base value of 1
rf: red factor, default: 1, multiply values by factor, proportional to base value of 1
gf: green factor, default: 1, multiply values by factor, proportional to base value of 1
bf: blue factor, default: 1, multiply values by factor, proportional to base value of 1
hv: hue value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
sv: saturation value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
lv: lightness/brightness value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
rv: red value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
gv: green value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
bv: blue value, default: 0, add value to values, linear from base value of 0 to a maximum value of 100
hmin: hue minimum threshold, default: 0, expected range (0, 100)
smin: saturation minimum threshold, default: 0, expected range (0, 100)
lmin: lightness/brightness minimum threshold, default: 0, expected range (0, 100)
rmin: red minimum threshold, default: 0, expected range (0, 100)
gmin: green minimum threshold, default: 0, expected range (0, 100)
bmin: blue minimum threshold, default: 0, expected range (0, 100)
hmax: hue maximum threshold, default: 0, expected range (0, 100)
smax: saturation maximum threshold, default: 0, expected range (0, 100)
lmax: lightness/brightness maximum threshold, default: 0, expected range (0, 100)
rmax: red maximum threshold, default: 0, expected range (0, 100)
gmax: green maximum threshold, default: 0, expected range (0, 100)
bmax: blue maximum threshold, default: 0, expected range (0, 100)
alpha: numeric, sets color alpha values
seed: integer, default: 42, set seed for generation of colors (n > given colors (palettes)) and colors ordering (see order)
order: default: 1, numeric (vector) to adjust colors order, -1: reverse order, 0: seeded random order, >1: shift order, c(-1, >1): reverse then shift order, or numeric vector as many colors to set custom order (if longer, vector shortened to n colors)
verbose: default: TRUE, mentions if and how many colors are generated

Value

sets colors in ggplot2 plotted object, see examples

Examples

## viridis ggplot2 examples Colorified 

## non-discrete
if (requireNamespace("ggplot2", quietly = TRUE)) {
  dsub <- subset(ggplot2::diamonds, x > 5 & x < 6 & y > 5 & y < 6)
  dsub$diff <- with(dsub, sqrt(abs(x - y)) * sign(x - y))

  d <- ggplot2::ggplot(dsub, ggplot2::aes(x, y, colour = diff)) + ggplot2::geom_point()
    d + scale_color_colorify(n = 4, colors = 'viridis') + ggplot2::theme_bw()


## discrete

  p <- ggplot2::ggplot(mtcars, ggplot2::aes(wt, mpg))
  p + ggplot2::geom_point(size = 4, ggplot2::aes(colour = factor(cyl))) +
    ggplot2::theme_bw() + scale_color_colorify(discrete = TRUE, colors = c('red', 'blue', 'yellow'))
