SPHSUgraphs

For applying Unit colour scales and other theme aesthetics to ggplot2 plots

Installation

You can install the development version of SPHSUgraphs from GitHub with:

# install.packages("devtools")
devtools::install_github("andrewbaxter439/SPHSUgraphs")

The Unit Palette

Use sphsu_show_colours() to show the range of named colours you can use:

library(SPHSUgraphs)
sphsu_show_colours()

Adding a palette

Colour and fill functions have four pre-installed palettes: \"main\", \"hot\", \"cool\" and \"mixed\". You can add a custom palette like so:

sphsu_palettes$newname <- sphsu_cols("Cobalt", "Thistle", "Leaf")

You can then use this new palette name in calls of scale_fill_sphsu and scale_colour_sphsu (see below).

Using in ggplot

Right now the main output of these functions is to apply colour and fill scales to your ggplot2 graphics, by adding a scale_ function at the end of your call.

Examples:

ggplot(iris, aes(Sepal.Width, Sepal.Length, col = Species)) +
  geom_point(size = 4) +
  scale_colour_sphsu()

ggplot(iris, aes(Sepal.Width, Sepal.Length, col = Sepal.Length)) +
  geom_point(size = 4) +
  scale_colour_sphsu("hot", discrete = FALSE)

ggplot(iris, aes(Sepal.Width, Sepal.Length, col = Sepal.Length)) +
  geom_point(size = 4) +
  scale_colour_sphsu("cool", discrete = FALSE)

ggplot(mpg, aes(manufacturer, fill = manufacturer)) +
  geom_bar() +
  theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
  scale_fill_sphsu(palette = "mixed", guide = "none")
