Multiple plot function — multiplot • ggspectra

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: character vector Title of the composite plot.
title.position: numeric or character, the horizontal position of the title.
title.fontsize: numeric
title.fontfamily: character e.g. "sans", "serif", "mono".
title.fontface: character e.g. "plain", "bold", "italic", "bold.italic".
title.colour: character e.g. "black", "red".

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.
