ridgeline

A function for creating ridgeline plots in base R

Why this package?

I created this package beacause I wanted to add the function on a document without displaying the full code and because I think there is no other package implementing ridgeline plots in base R. However, I recommend you using ggridges (for ggplot2), which has more features than this package.

The package is based on a code by Karolis Koncevicius.

Installation

# install.packages("remotes")
remotes::install_github("R-CoderDotCom/ridgeline@main")

library(ridgeline)

Usage

Basic ridgeline plot

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

# Default ridgeline plot
ridgeline(x, y)

Bandwidth selection

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

# Default ridgeline plot
ridgeline(x, y, bw = 50)

Colors customization

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

# Default ridgeline plot
ridgeline(x, y,
          palette = hcl.colors(6, palette = "viridis", alpha = 0.9), # Colors of the areas
          border = hcl.colors(6, palette = "viridis", alpha = 0.9))  # Border colors for the areas

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

# Default ridgeline plot
ridgeline(x, y,
          col = 4) # Color of the horizontal lines

Custom labels

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

ridgeline(x, y,
          labels = c("c", "h", "l", "m", "s", "s"))

Add the mode

# Numeric variable
x <- chickwts$weight

# Categorical variable
y <- chickwts$feed

ridgeline(x, y,
          mode = TRUE)
