Usage

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)))

Arguments

plots	list of ggplots
nrow	number of rows
ncol	number of columns
widths	list of requested widths
heights	list of requested heights
byrow	logical, fill by rows
top	optional string, or grob
bottom	optional string, or grob
left	optional string, or grob
right	optional string, or grob
padding	unit of length one, margin around annotations
clip	argument of gtable
draw	logical: draw or return a grob
newpage	logical: draw on a new page
debug	logical, show layout with thin lines
labels	character labels used for annotation of subfigures
label.args	label list of parameters for the formatting of labels

Value

gtable of aligned plots

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'))
