fardist(X, ...)
"fardist"(X, ..., squared=FALSE)
"fardist"(X, ..., squared=FALSE)as.mask to determine
the pixel resolution, if required.
TRUE, the squared distances will be
returned.
fardist.owin, a pixel image (object of class "im").For fardist.ppp, a numeric vector.
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.
