ggrain is an R-package that allows you to create Raincloud plots - following the 'Grammar of Graphics' (i.e., ggplot2) - that are:

• Highly customizable
• Connect longitudinal observations
• Handles Likert data
• Allows mapping of a covariate.

ggrain was developed by Nicholas Judd, Jordy van Langen, Micah Allen, and Rogier Kievit.

    ggrain: A Rainclouds Geom for 'ggplot2'.
    R package version 0.0.4.
    CRAN 2023, https://doi.org/10.32614/CRAN.package.ggrain,
    https://CRAN.R-project.org/package=ggrain

ggplot(iris, aes(x = 1, y = Sepal.Length)) +
  geom_rain()

There are two ways to install this package.

1. Download the CRAN version

install.packages("ggrain")

library(ggrain)

2. Download through GitHub

if (!require(remotes)) {
    install.packages("remotes")
}
remotes::install_github('njudd/ggrain')

library(ggrain)

1. Raincloud per group

   ggplot(iris, aes(x = Species, y = Sepal.Length, fill = 	Species)) +
   	geom_rain(rain.side = 'l')

2. Different groups overlapped

   ggplot(iris, aes(x = 1, y = Sepal.Length, fill = Species)) +
   	geom_rain(alpha = .5)

For a complete overview of ggrain such as a 2-by-2 raincloud plot or multiple repeated measures, please see our Vignette.

geom_rain is a combination of 4 different ggplot2 geom's (i.e., point, line, boxplot & violin).

• id.long.var: a grouping variable to connect the lines by
• cov: a covariate to remap the color of the points
• Likert: True or False response which adds y jittering
• rain.side: Which side to display the rainclouds: 'l' for left, 'r' for right and 'f' for flanking

Specific geom arguments can be passed with a list to any of the 4 geom's with the argument {point/line/boxplot/violin}.args. Position-related arguments (e.g., jittering, nudging & width) can be passed with {point/line/boxplot/violin}.args.pos, see the help file of ?geom_rain for defaults

In 2021, NWO (Dutch research council) announced their inaugural NWO Open Science Fund. The Open Science Fund aims to support researchers to develop, test and implement innovative ways of making research open, accessible, transparent and reusable, covering the whole range of Open Science. The Raincloud plots team was awarded this fantastic initiative and is specifically working on:

• Creating the ggrain R-package
• Creating an interactive R Shiny application raincloudplots
• Integrating Raincloudplots in JASP Statistics
• Organzing globally accessible, online workshops to help people create raincloudplots and improve their data visualizations in general.

You can read more about our awarded project here: https://www.nwo.nl/en/projects/203001011 or you can watch the online webinar hosted by NWO about our project:

• through our initial raincloudplots package
• through the newest R-package ggrain
• through our R Shiny application: raincloudplots
