How to show a legend as if it was a plot in a matrix of plots (ggplot2)?

I'm using the ggarrange() function of the egg package to display the plots like this. Thanks for the help.

CodePudding user response：

One option to achieve your desired result would be to switch to the patchwork package:

Using mtcars as example data:

library(ggplot2)
library(patchwork)

p <- ggplot(mtcars, aes(factor(cyl), mpg, fill = factor(am)))  
  geom_boxplot()


list(p, p, p) |>
  wrap_plots(nrow = 2)  
  guide_area()  
  plot_layout(guides = "collect")
