Colour scales for ggplot2

Description

Colour and fill scales for ggplot2 plots, using object of class palettehex.

Usage

scale_colour_palettehex_d(x, which = 1, reverse = FALSE, ...)

scale_color_palettehex_d(x, which = 1, reverse = FALSE, ...)

scale_fill_palettehex_d(x, which = 1, reverse = FALSE, ...)

scale_colour_palettehex_c(x, which = 1, reverse = FALSE, ...)

scale_color_palettehex_c(x, which = 1, reverse = FALSE, ...)

scale_fill_palettehex_c(x, which = 1, reverse = FALSE, ...)

Arguments

x	object of class palettehex
which	selection of which palette of a set to choose. Either by name, id or numeric index.
reverse	logical. If scale should b reversed (default: FALSE)
...	arguments to be passed to discrete_scale

Details

The palettehex class is a data.frame of many palettes. This function takes such a data.frame and a choice of palette by name, id or numeric index can be made for the scale.

Value

ggplot2-proto

library(ggplot2)

x <- get_popular_palettes()

ggplot(mtcars, aes(mpg)) +
