Splits a graphics display into multiple screens for tree-specific functions
that require more than one screen.
USAGE:
tree.screens(figs, screen.arg = 0, ...)
OPTIONAL ARGUMENTS:
figs
a multiple figure vector like mfrow or mfcol, e.g,
c(n,m), or an N by 4 matrix where N is the number of
screens and each row specifies the position of a screen on
the display; the first two columns specify the left and
right coordinates (in the 0, 1, 0, 1 plane) for the
screens, and the third and fourth columns the bottom and
top coordinates.
screen.arg
screen to split up. By default it carves up the current
screen, which initially is the entire display (denoted as screen 0).
VALUE:
Called without arguments this function sets up a generic partition
of the graphics area for the tree-specific functions that
require more than one screen.

split.screen documentation for
