frame()
new is set to
TRUE,
frm is incremented,
and
mfg is incremented when there are multiple plots.
In multiple figure mode,
frame will
advance to the next figure.
It takes two calls to
frame to skip a figure: the first goes to the
next figure, and the second call skips to the figure after that.
This function does not concern memory frames - see
sys.call for
such functions.
