Retrieve colour hex values from a palette

Description

Retrieve colour hex values from a palette

Usage

get_colours(
  colour_names = "red",
  palette = r2dii.colours::palette_1in1000_plot
)

Arguments

colour_names	Character string or a vector of character strings with names of colours for which you want to retrieve the hex values.
palette	The dataframe from which the hex values are retrieved. It should contain columns label and hex.

Value

A vector of strings with hex codes in order specified by colour_names.

Examples

# use default palette
get_colours(c("red", "blue"))

# specify which palette to use
get_colours(c("red", "green"), palette = palette_1in1000_goodbad)

Custom 2DII colour and fill scales

Description

A custom discrete colour and fill scales with colours from 2DII palettes.

Usage

scale_colour_2dii(
  palette = c("2dii", "1in1000", "pacta", "survey"),
  colour_groups = NULL,
  labels = NULL,
  ...
)

scale_fill_2dii(
  palette = c("2dii", "1in1000", "pacta", "survey"),
  colour_groups = NULL,
  labels = NULL,
  ...
)

Arguments

palette	String with the name of the colour scale to be used. If not specified then the general 2dii scale is used
colour_groups	A vector containing groups variable to which colours are assigned. It is needed when the data assigned to colour aesthetic are not all contained in colour aliases of the palette. By default it is null and then only names in data that are also found in colour aliases for the palette are coloured.
labels	Labels parameter to be used in ggplot2::scale_colour_manual. By default it is set to an internal function beaudetifying the labels.
...	Other parameters passed on to ggplot2::discrete_scale().

Value

An object of class "ScaleDiscrete".

Examples

library(ggplot2, warn.conflicts = FALSE)
library(r2dii.plot, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)

sda %>%
  filter(emission_factor_metric == "projected") %>%
  ggplot() +
  geom_line(aes(x = year, y = emission_factor_value, colour = sector)) +
  scale_colour_2dii()

mpg %>%
  ggplot() +
  geom_histogram(aes(cyl, fill = class), position = "dodge", bins = 5) +
  scale_fill_2dii()

market_share %>%
  filter(sector == "automotive", year %in% c(2020, 2025), metric == "projected") %>%
  ggplot() +
  geom_bar(
    stat = "identity",
    aes(x = year, y = technology_share, fill = technology)
  ) +
  scale_fill_2dii(palette = "pacta")
