panes: Prepare a "panel" type layout

In plotrix/plotrix: Various Plotting Functions

Prepare a "panel" type layout

Description

Split the graphics device into a "panel" type layout for a group of plots

Usage

 panes(mat=NULL,widths=rep(1,ncol(mat)),heights=rep(1,nrow(mat)),
  nrow=2,ncol=2,mar=c(0,0,1.6,0),oma=c(2.5,1,1,1))

Arguments

mat	A matrix representing the number of panes to be created and their order of plotting.
widths,heights	The widths and heights of the panes. See ‘⁠layout⁠’.
nrow,ncol	The numbers of rows and columns in the layout. See ‘⁠par(mfrow)⁠’.
mar	The margins for each plot in the panes.
oma	The outer margins for the entire group of panes.

Details

‘⁠panes⁠’ combines the information for displaying a set of plots in a "panel" layout. The default values will usually produce the desired result by calling ‘⁠par(mfrow)⁠’. If ‘⁠mat⁠’ is not NULL, the ‘⁠layout⁠’ function will be called instead of ‘⁠par(mfrow)⁠’. The two methods are included for the convenience of the user.

Note that ‘⁠panes⁠’ does not produce any plots and that the user must call ‘⁠tab.title⁠’ to get the "look" of the panel plot. The overall title is usually centered at the left edge (as in the example) or in the center of one of the plots in the bottom row.

Value

The values of ‘⁠par⁠’ options that existed when ‘⁠panes⁠’ was called. This list is usually used to restore those values.
