perm.ds.focal: Data stream permutation for focal sampling data .

In SebastianSosa/ant: Animal Network Toolkit Software

Data stream permutation for focal sampling data .

Description

Warning, the original function (Farine 2017) uses a control factor, the number of focals and the ids of the focals.

Usage

perm.ds.focal(
  df,
  focal,
  ctrl = NULL,
  alters,
  nperm,
  progress = T,
  method = "sri"
)

Arguments

df	a data frame.
focal	an integer indicating the column of the focal.
ctrl	a numeric vector indicating the control factors.
alters	an integer indicating the column of focal's alters.
nperm	an integer indicating the number of permutations.
progress	a boolean indicating if the permutation process must be visible.
method	a string indicating the association index to compute: 'sri' for Simple ratio index: x/x+yAB+yA+yB 'hw' for Half-weight index: x/x+yAB+1/2(yA+yB) 'sr' for Square root index:x/sqr((x+yAB+yA)(x+yAB+yB))

Details

Pre-network permutation for focal sampling data, and for symmetric behaviour only.
