ggplot objects. |
plotlist |
A list of ggplot objects. |
ncol |
How many columns in the grid of plots? Ignored if 'layout' is specified. |
byrow |
Should plots be printed by rows or by columns? Ignored if 'layout' is specified. |
layout |
A matrix of indices of plots specifying where in the grid the plots should be printed. See details. |
title |
A string denoting the title. |
If 'layout' is specified, 'ncol' and 'byrow' will be ignored. Each plot will then be printed in the grid location corresponding to the entry/entries in 'layout' which list(s) its index in the function call. E.g. the first plot will be plotted in the grid corresponding to where '1' shows up in 'layout'. If any entry is '0', then nothing will be plotted there. It is possible to have a plot span more than one place in the grid; see the examples.
Nothing is returned; however, the ggplot objects are printed.
