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.
