sm_raincloud: Raincloud Plot

In smin95/sesplot: Create Standalone and Composite Plots in 'ggplot2' for Publications

Raincloud Plot

Description

Creates a raincloud plot, a combination of jittered points, boxplots, and violin plots. Inspired by the 'raincloudplots' R package by Jordy van Langen, this function offers enhanced customization and automatic sorting of data based on the x-axis factor levels.

This function allows detailed control over the aesthetics of individual components (boxplot, violin, and points) and provides options to adjust layout and orientation.

Usage

sm_raincloud(
  ...,
  boxplot.params = list(),
  violin.params = list(alpha = 0.3, color = "transparent"),
  point.params = list(alpha = 1, size = 3, shape = 21, color = "transparent"),
  which_side = "r",
  sep_level = 2,
  point_jitter_width = 0.12,
  vertical = TRUE,
  points = TRUE,
  borders = TRUE,
  legends = FALSE,
  seed = NULL,
  forget = FALSE
)

Arguments

...	Additional aesthetic parameters applied across all elements (points, boxplot, and violin plot). Optional.
boxplot.params	A list of parameters for customizing the boxplot. Common options include: fill: Fill color of the boxplot. color: Outline color of the boxplot. alpha: Transparency level of the boxplot. width: Width of the boxplot. Default: list().
violin.params	A list of parameters for customizing the violin plot. Common options include: alpha: Transparency level of the violin plot. color: Outline color of the violin plot. fill: Fill color of the violin plot. Default: list(alpha = 0.3, color = 'transparent').
point.params	A list of parameters for customizing individual points. Common options include: alpha: Transparency level of the points. size: Size of the points. shape: Shape of the points. color: Outline color of the points. Default: list(alpha = 1, size = 3, shape = 21, color = 'transparent').
which_side	Specifies the side of the violin and boxplots. Options: 'right': Displays elements on the right side (default). 'left': Displays elements on the left side. The 'mixed' option has been removed due to limited usage.
sep_level	A numeric value (0-4) controlling the separation level among the boxplot, violin plot, and points: 0: All elements are clustered together. 4: All elements are maximally separated. Intermediate values (1-3) provide varying levels of separation. Default: 2.
point_jitter_width	A numeric value determining the horizontal jitter for individual points: If set to 0, points are aligned along the y-axis without jitter. Default: 0.12.
vertical	Logical. Specifies the orientation of the plot: TRUE: Vertical orientation (default). FALSE: Horizontal orientation.
points	Logical. Determines whether individual points are displayed: TRUE: Display points (default). FALSE: Hide points.
borders	Logical. Determines whether grid borders are displayed: TRUE: Display borders (default). FALSE: Remove borders.
legends	Logical. Determines whether legends are displayed: TRUE: Display legends. FALSE: Hide legends (default).
seed	A numeric value to set a random seed for reproducible jittered points. Default: NULL (no seed).
forget	Logical. Determines whether to apply the default aesthetic parameters: TRUE: Ignore default aesthetic parameters (boxplot.params, violin.params, and point.params) and apply only user-supplied customizations. FALSE: Merge user-supplied customizations with the defaults (default).

Value

A list of ggplot2 layers for creating a raincloud plot.

Examples

library(ggplot2)
library(smplot2)

set.seed(2) # generate random data
day1 = rnorm(20,0,1)
day2 = rnorm(20,5,1)
day3 = rnorm(20,6,1.5)
day4 = rnorm(20,7,2)
Subject <- rep(paste0('S',seq(1:20)), 4)
Data <- data.frame(Value = matrix(c(day1,day2,day3,day4),ncol=1))
Day <- rep(c('Day 1', 'Day 2', 'Day 3', 'Day 4'), each = length(day1))
df2 <- cbind(Subject, Data, Day)

ggplot(data=df2, aes(x = Day, y = Value, color = Day, fill = Day)) +
sm_raincloud() +
 xlab('Day')  +
 scale_fill_manual(values = sm_palette(4))
