The goal of rcartocolor is to provide color schemes for maps and other graphics designed by CARTO as described at https://carto.com/carto-colors/.

Installation

Get the released version from CRAN:

install.packages("rcartocolor")

Get the development version from github:

# install.packages("remotes")
remotes::install_github("Nowosad/rcartocolor")

Examples

Display a CARTOcolor palette:

library(rcartocolor)
display_carto_pal(7, "Vivid")

Create a CARTOcolor palette:

my_colors = carto_pal(7, "Burg")
my_colors
#> [1] "#ffc6c4" "#f4a3a8" "#e38191" "#cc607d" "#ad466c" "#8b3058" "#672044"

Display all of the CARTOcolor palettes:

Only display colorblind friendly palettes:

display_carto_all(colorblind_friendly = TRUE)

ggplot2

The rcartocolor package contains four ggplot2 color scales: two for continuous data - scale_fill_carto_c, scale_color_carto_c and two for discrete data - scale_fill_carto_d, scale_color_carto_d:
