SpaDES.tools-package

Categorized overview of the SpaDES.tools package

adj.raw() adj()

Fast `adjacent` function, and Just In Time compiled version

cir()

Identify pixels in a circle or ring (donut) around an object.

.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 xy coordinates of every locus
