What's inside patchwork

  1. Install patchwork

    main

    You can install patchwork from CRAN using the standard install.packages() function. If you prefer the development version, you can install it from GitHub using devtools::install_github().

    # From CRAN
install.packages('patchwork')

# From GitHub (development version)
# install.packages("devtools")
devtools::install_github("thomasp85/patchwork")

  2. Combine ggplots using patchwork

    main

    The core usage of patchwork is to combine separate ggplot2 objects by using arithmetic operators. This allows you to arrange plots in simple rows, columns, or complex nested layouts with full alignment.

    library(ggplot2)
library(patchwork)

p1 <- ggplot(mtcars) + geom_point(aes(mpg, disp))
p2 <- ggplot(mtcars) + geom_boxplot(aes(gear, disp, group = gear))

# Combine plots side-by-side
p1 + p2

# Create complex nested layouts using | (horizontal) and / (vertical) operators
p3 <- ggplot(mtcars) + geom_smooth(aes(disp, qsec))
p4 <- ggplot(mtcars) + geom_bar(aes(carb))

(p1 | p2 | p3) /
      p4
