cirSpecialQuick

.cirSpecialQuick

Raster on which the circles are built.

landscape

Numeric. An alternative to <code>coords</code>. These are the indices on
<code>landscape</code> to initiate this function. See <code>coords</code>. Default is one
point in centre of <code>landscape</code>..

loci

Numeric vector of length 1 or same length as coords

maxRadius

Numeric vector of length 1 or same length as <code>coords</code>. Default is
<code>maxRadius</code>, meaning return all cells that are touched
by the narrow ring at that exact radius. If smaller than <code>maxRadius</code>,
then this will create a buffer or donut or ring.

minRadius

This is a very fast version of cir with allowOverlap = TRUE, allowDuplicates = FALSE,
returnIndices = TRUE, returnDistancse = TRUE, and includeBehaviour = "excludePixels".
It is used inside spread2, when asymmetry is active. The basic algorithm is to run cir
just once, then add to the xy coordinates of every locus

Provides GIS and map utilities, plus additional modeling tools for
developing cellular automata, dynamic raster models,
and agent based models in 'SpaDES'.
Included are various methods for spatial spreading, spatial agents, GIS
operations, random map generation, and others.
See '?SpaDES.tools' for an categorized overview of these additional tools.
