Description

Grid based; allows multiple plots arraged in a matrix and printed to any R device. ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects)

Usage

multiplot(
  ...,
  plotlist = NULL,
  ncol = 1,
  cols = ncol,
  layout = NULL,
  title = "",
  title.position = "left",
  title.fontsize = 12,
  title.fontfamily = "sans",
  title.fontface = "bold",
  title.colour = "black"
)

Arguments

...

one or more ggplot objects.

plotlist

list of ggplot objects.

ncol, cols

numerical Number of columns in layout.

layout

A numeric matrix specifying the layout. If present, 'cols' is ignored.

title

title.colour

Details

ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects) If the layout is something like matrix(c(1,2,3,3), nrow=2, byrow=TRUE), then plot 1 will go in the upper left, 2 will go in the upper right, and 3 will go all the way across the bottom.
