Named arguments controlling the plot. See Details. |
These are methods for the generic functions
print
,
plot
,
contour
and persp
for the class "distfun"
of distance functions.
See distfun
for explanation about this class.
The print
method prints a description of the domain of the
distance function and the spatial object of which it is the distance
function. Any additional arguments ...
are ignored.
The plot
, contour
and persp
methods first convert
x
to a pixel image object using as.im
,
then display it using plot.im
, contour.im
or
persp.im
.
Additional arguments ...
are either
passed to as.im.function
to
control the spatial resolution of the pixel image, or passed to
contour.im
,
persp.im
or
plot.im
to control the appearance of the plot.
