For a point pattern on a linear network, this function draws the coordinates of the points only, on the existing plot display.

x is a point pattern on a linear network, then
points(x) plots the spatial coordinates of the points only,
on the existing plot display,
without plotting the underlying network.
It is an error to call this function if a plot has not yet been
The spatial coordinates are extracted and passed to

The more usual way to plot the points is using
plot(x) would plot both the points and the
underlying network, while
plot(x, add=TRUE) would plot only the
points. The interpretation of arguments controlling the colours and
plot symbols is different here: they determine a symbol map, as explained
