Renders multiple ggplots on a single page.
multiplot(..., plotlist = NULL, cols = 1, layout = NULL)
Comma-separated ggplot
objects.
A list of ggplot
objects - an alternative to the comma-separated argument above.
Number of columns of plots on the page.
A matrix specifying the layout. If present, 'cols' is ignored. 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.
