scale_color_phl: City of Philadelphia color scales

In CityOfPhiladelphia/rphl: R Functions for City of Philadelphia

Description

These functions provide ggplot2-compatible color and fill scales using City of Philadelphia colors, available at https://standards.phila.gov/guidelines/design-development/brand-elements/color-palette/. The underlying code is adapted from @drsimonj's tutorial at https://drsimonj.svbtle.com/creating-corporate-colour-palettes-for-ggplot2.

Usage

scale_color_phl(..., palette = "main", discrete = T, reverse = F,
  pal_list = phl_pal_list, named = F)

scale_fill_phl(..., palette = "main", discrete = T, reverse = F,
  pal_list = phl_pal_list, named = F)

Arguments

...	options passed to scale_color_manual or scale_color_gradientn
palette	character, which palette to use. Options are "main", "dark", "light", "blues" and "grays".
discrete	logical, whether palette is discrete or continuous. Continuous will interpolate between colors; discrete has a maximum number of values.
reverse	logical, whether to reverse the order of the palette.
pal_list	Named list of palettes, used by palette argument. Each element is a vector of hex codes.
named	logical, whether the colors in the palette have names corresponding to the data. This is usually not true.

Functions

• scale_color_phl: Color scale

• scale_fill_phl: Fill scale

Examples

library(ggplot2)
p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, color = Species)) +
  geom_point(size = 3)
p + scale_color_phl()

p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, color = Petal.Length)) +
  geom_point(size = 3)
p + scale_color_phl("blues", discrete = F)
p + scale_color_phl("blues", discrete = F, reverse = T)

p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, fill = Species)) +
  geom_point(aes(size = Petal.Width), shape = 21)

p + scale_fill_phl()

p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, fill = Petal.Length)) +
  geom_point(aes(size = Petal.Width), shape = 21)
p + scale_fill_phl("blues", discrete = F)
p + scale_fill_phl("blues", discrete = F, reverse = T)
