patchwork 
The goal of patchwork is to make it ridiculously simple to combine
separate ggplots into the same graphic. As such it tries to solve the
same problem as gridExtra::grid.arrange() and cowplot::plot_grid but
using an API that incites exploration and iteration, and scales to
arbitrily complex layouts.
Installation
You can install patchwork from CRAN using
install.packages('patchwork'). Alternatively you can grab the
development version from github using devtools:
# install.packages("devtools")
devtools::install_github("thomasp85/patchwork")Basic example
The usage of patchwork is simple: just add plots together!
library(ggplot2)
library(patchwork)
p1 <- ggplot(mtcars) + geom_point(aes(mpg, disp))
p2 <- ggplot(mtcars) + geom_boxplot(aes(gear, disp, group = gear))
p1 + p2
patchwork provides rich support for arbitrarily complex layouts with
full alignment. As an example, check out this very readable code for
nesting three plots on top of a third:
p3 <- ggplot(mtcars) + geom_smooth(aes(disp, qsec))
p4 <- ggplot(mtcars) + geom_bar(aes(carb))
(p1 | p2 | p3) /
p4
