Renders multiple ggplots on a single page.

Usage

multiplot(..., plotlist = NULL, cols = 1, layout = NULL)

Arguments

...

Comma-separated ggplot objects.

plotlist

A list of ggplot objects - an alternative to the comma-separated argument above.

cols

Number of columns of plots on the page.

layout

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.
