Internal helpers

Description

Not for users. A function to setnames and rbindlist that is used in spread2.

Usage

rbindlistDtDtpot(
  dt,
  dtPotential,
  returnFrom,
  needDistance,
  dtPotentialColNames
)

reorderColsWDistance(needDistance, dtPotential, dtPotentialColNames)

angleQuality(from, to, landscape, actualAsymmetryAngle)

asymmetryAdjust(angleQualities, quantity, actualAsymmetry)

Arguments

dt	a data.table object
dtPotential	a data.table object
returnFrom	logical
needDistance	logical
dtPotentialColNames	character vector.
from	vector of cell locations which are the "from" or starting cells
to	vector of same length as from which are the "to" or receiving cells
landscape	RasterLayer passed from spread2.
actualAsymmetryAngle	Angle in degrees, either a vector length 1 or vector NROW(dtPotential).
angleQualities	Matrix. The output from angleQuality
quantity	Variable of interest to adjust, e.g., spreadProb
actualAsymmetry	Asymmetry intensity. Derived from asymmetry arg in spread2
