In the spatstat package, an object of class "symbolmap"
defines a mapping between data and graphical symbols.
If a plot command plot(x, ...) has been issued,
and if the arguments were not sufficient to determine the
symbol map that should be used, then default.symbolmap(x, ...)
will be executed to determine the default symbol map.
The function default.symbolmap is generic, with a method
for point patterns (class "ppp") and possibly for other
classes.
