ggpattern provides custom ggplot2 geoms which support filled areas with geometric and image-based patterns.

Reading the articles/vignettes on the package website is probably the best way to get started.

Feature Summary

  • Custom versions of (almost) all the geoms from ggplot2 which have a region which can be filled.
  • A suite of aesthetics for controlling the pattern appearance (e.g. pattern_alpha)
  • The ability to include user-defined patterns

Installation

You can install the development version from GitHub with the instructions below:

# install.packages("remotes")
remotes::install_github("coolbutuseless/ggpattern")

An installation error is highly unlikely to be an issue with ggpattern itself. Please don’t open up a Github Issues unless you are sure it is an issue with ggpattern itself. If you have an error installing the package we strongly suggest that you look at all your error messages more closely to figure out which package dependency is failing to install and why. See https://thomasadventure.blog/posts/install-r-packages/ for more info on installing R packages.

Quickstart

  1. Take an existing plot which contains a geom with a fillable area e.g geom_col().
  2. Use the ggpattern version of the geom e.g. ggpattern::geom_col_pattern() instead of ggplot2::geom_col()
  3. Set the aesthetic pattern to your choice of pattern e.g pattern = 'stripe', and set other options using pattern_* aesthetics
df <- data.frame(level = c("a", "b", "c", 'd'), outcome = c(2.3, 1.9, 3.2, 1))

ggplot(df) +
  geom_col_pattern(
    aes(level, outcome, pattern_fill = level), 
    pattern = 'stripe',
    fill    = 'white',
    colour  = 'black'
  ) +
  theme_bw(18) +
  theme(legend.position = 'none') + 
  labs(
    title    = "ggpattern::geom_pattern_col()",
    subtitle = "pattern = 'stripe'"
  ) +
  coord_fixed(ratio = 1/2)
