ggarrange

Arrange multiple ggplot objects on a page, aligning the plot panels.

ggarrange(..., plots = list(...), nrow = NULL, ncol = NULL,
  widths = NULL, heights = NULL, byrow = TRUE, top = NULL,
  bottom = NULL, left = NULL, right = NULL, padding = unit(0.5,
  "line"), clip = "on", draw = TRUE, newpage = TRUE, debug = FALSE,
  labels = NULL, label.args = list(gp = grid::gpar(font = 4, cex =
  1.2)))

Examples

p1 <- ggplot(mtcars, aes(mpg, wt, colour = factor(cyl))) +
  geom_point()
p2 <- ggplot(mtcars, aes(mpg, wt, colour = factor(cyl))) +
  geom_point() + facet_wrap( ~ cyl, ncol=2, scales = 'free') +
  guides(colour='none') +
  theme()
ggarrange(p1, p2, widths = c(2,1), labels = c('a', 'b'))
