SpaDES.tools-package | Categorized overview of the 'SpaDES.tools' package
.cirSpecialQuick | This is a very fast version of 'cir' with 'allowOverlap = TRUE', 'allowDuplicates = FALSE', 'returnIndices = TRUE', 'returnDistances = TRUE', and 'includeBehavior = "excludePixels"'. It is used inside 'spread2', when asymmetry is active. The basic algorithm is to run 'cir' just once, then add to the x,y coordinates of every locus.
.pointDistance | Alternative point distance (and direction) calculations
adj | Fast 'adjacent' function, and Just In Time compiled version
agentLocation | 'SELES' - Agent Location at initiation
cir | Identify pixels in a circle or ring (doughnut) around an object.
