ggifau

The goal of ggifau is to produce ggplot2 graphs which conform to the graphical profile of the Institute for Evaluation of Labour Market and Education Policy (IFAU) policy reports.

Installation

You can install the development version of ggifau like so:

# install.package("devtools")
devtools::install_github("adrianadermon/ggifau")

Usage

Load the package:

library(ggplot2)
library(ggifau)
#> Loading required package: svglite

To apply the full IFAU theme, first run

set_geoms_ifau()

to change the default options for some ggplot2 geoms. Then use the theme_ifau() function in your call to ggplot2:

ggplot(mtcars, aes(x = disp, y = mpg, color = factor(carb), shape = factor(carb))) +
  geom_point() +
  theme_ifau()

This applies some theme changes to the background, axes, text, grid and so on. In addition, it applies custom scales for colors, marked shapes, and lines. The following call, which applies each scale and the minimal theme separately, is equivalent:

ggplot(mtcars, aes(x = disp, y = mpg, color = factor(carb), shape = factor(carb))) +
  geom_point() +
  scale_color_ifau() +
  scale_fill_ifau() +
  scale_shape_ifau() +
  scale_linetype_ifau() +
  theme_ifau_minimal()

Below are some further examples.

ggplot(mtcars, aes(x = disp, y = mpg, color = factor(carb), linetype = factor(carb))) +
  geom_line() +
  theme_ifau()

ggplot(mtcars, aes(x = gear, y = mpg, fill = factor(carb))) +
  geom_col(position = position_dodge()) +
  theme_ifau()

ggplot(mtcars, aes(x = mpg)) +
  geom_histogram(bins = 30) +
  theme_ifau()

ggplot(mtcars, aes(x = disp, y = mpg, color = factor(carb), shape = factor(carb), linetype = factor(carb))) +
  geom_line() +
  geom_point() +
  geom_vline(aes(xintercept = 200)) +
  theme_ifau()

To save a plot to file, use the ifau_save() function. This is a simple wrapper for the ggsave function from the ggplot2 package, which sets the default width and height to appropriate values for IFAU reports.
