Farthest Distance to Boundary of Window
Computes the farthest distance from each pixel, or each data point, to the boundary of the window.
fardist(X, ...) ## S3 method for class 'owin' fardist(X, ..., squared=FALSE) ## S3 method for class 'ppp' fardist(X, ..., squared=FALSE)

The function fardist
is generic, with methods for
the classes owin
and ppp
.
For a window W
, the command fardist(W)
returns a pixel image in which the value at each pixel
is the largest distance from that pixel to the boundary of
W
.
For a point pattern X
, with window W
, the
command fardist(X)
returns a numeric vector
with one entry for each point of X
, giving the
largest distance from that data point to the boundary of W
.
For fardist.owin
, a pixel image (object of class "im"
).
For fardist.ppp
, a numeric vector.
