Disable cowplot default for ggplots

Question

The ggplot2 add-on package, cowplot, has a nice function for plotting multiple plots called plot_grid(). Here\'s plot_grid()

Answer 1

As mentioned in the comments, once you've installed the cowplot package you can load the plot_grid() function with the :: operator (see What are the double colons (::) in R?) and cowplot won't change any ggplot2 defaults.

> plot_a <- ggplot(mtcars, aes(mpg, wt)) + geom_point()
> plot_b <- ggplot(mtcars, aes(mpg, disp)) + geom_point()
> plot_grid(plot_a, plot_b, labels = c("A", "B"))
Error in plot_grid(plot_a, plot_b, labels = c("A", "B")) : 
  could not find function "plot_grid"

> cowplot::plot_grid(plot_a, plot_b, labels = c("A", "B"))

The issue comes when you load the entire cowplot package with library() or require().
