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.
