Methods for Spatial Functions
Description
Methods for objects of the class "funxy".
Usage
## S3 method for class 'funxy'
contour(x, ...)
## S3 method for class 'funxy'
persp(x, ...)
## S3 method for class 'funxy'
plot(x, ...)
Arguments
x |
Object of class |
... |
Named arguments controlling the plot. See Details. |
Details
These are methods for the generic functions
plot,
contour
and persp
for the class "funxy" of spatial functions.
Objects of class "funxy" are created, for example,
by the commands distfun and funxy.
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.
Value
NULL.
