palettes is an R package for working with colour vectors and colour palettes. There are three main goals to the palettes package, each described in a vignette:
To provide a new family of colour classes
(palettes_colour and palettes_palette) that
always print as hex codes with colour previews;
vignette("palettes").
To provide a comprehensive library of methods for working with
colour vectors and colour palettes, including methods for ggplot2,
vignette("ggplot2"); gt, vignette("gt");
biscale, vignette("biscale"); and other colour packages,
vignette("compatibility").
To make it easy for anyone to make their own colour palette
package; vignette("creating-packages"). Colour palette
packages made with palettes exist solely for the purpose of distributing
colour palettes and get access to all the features of palettes for
free.
Install palettes from CRAN with:
install.packages("palettes")Install the development version from GitHub or R-universe with:
# Install from GitHub
# install.packages("remotes")
remotes::install_github("mccarthy-m-g/palettes")
# Install from R-universe
install.packages("palettes", repos = "https://mccarthy-m-g.r-universe.dev")Install the WebAssembly version for use in WebR applications with:
# Install CRAN version from r-wasm
install.packages("palettes", repos = "https://repo.r-wasm.org")
# Install development version from R-universe
install.packages(
"palettes",
repos = c("https://mccarthy-m-g.r-universe.dev", "https://repo.r-wasm.org")
)library(palettes)Colours can be specified by name (as listed by
grDevices::colours()):
pal_colour("red")
Or by hex code:
pal_colour("#FF0000")
Multiple colours can be specified at once as a character vector:
pal_colour(c("#a00e00", "#d04e00", "#f6c200", "#0086a8", "#132b69"))
Named colour palettes can be specified in the same way:
pal_palette(
egypt = c("#dd5129", "#0f7ba2", "#43b284", "#fab255"),
java = c("#663171", "#cf3a36", "#ea7428", "#e2998a", "#0c7156")
)
Colours also print nicely in tibbles:
as_tibble(pal_colour(c("#dd5129", "#0f7ba2", "#43b284", "#fab255")))
