fish colour scales

Uses the fish color scale.

scale_color_fish(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE
)

scale_colour_fish(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE
)

scale_colour_fish_d(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_color_fish_d(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_fill_fish_d(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_fill_fish(
  option = "Centropyge_loricula",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE
)

Arguments

option	A character string indicating the fish species to use.
...	parameters to discrete_scale or scale_fill_gradientn
alpha	pass through parameter to fish
begin	The (corrected) hue in [0,1] at which the fish colormap begins.
end	The (corrected) hue in [0,1] at which the fish colormap ends.
direction	Sets the order of colors in the scale. If 1, the default, colors are as output by fish_pal. If -1, the order of colors is reversed.
discrete	generate a discrete palette? (default: FALSE - generate continuous palette)

Details

For discrete == FALSE (the default) all other arguments are as to scale_fill_gradientn or scale_color_gradientn. Otherwise the function will return a discrete_scale with the plot-computed number of colors.

Examples

library(ggplot2)
library(fishualize)


ggplot(diamonds, aes(factor(cut), fill=factor(cut))) +
geom_bar() +
scale_fill_fish(discrete = TRUE, option = "Centropyge_loricula")

ggplot(mtcars, aes(factor(gear), fill=factor(carb))) +
geom_bar() +
scale_fill_fish(discrete = TRUE, option = "Trimma_lantana")

ggplot(mtcars, aes(x = mpg, y = disp, colour = drat)) +
geom_point(size = 4) +
scale_colour_fish(option = "Ostracion_cubicus", direction = -1)
