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
.

f <- distfun(letterR)
contour(f)
B <- owin(c(1,5), c(-1, 4))
contour(f, W=B)
persp(f, W=B, theta=40, phi=40, border=NA, shade=0.7)
