perm.double.focal {ANTs} R Documentation

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.double.focal(
obs,
ego,
alters,
focal,
nperm,
progress = FALSE,
index = "sri",
measure,
test = "median",
df = NULL,
dfid = NULL,
rf,
...
)


Arguments

 obs a data frame of focal observations. ego an integer indicating the column of the focal id for the obs. alters an integer indicating the column of focal's alters in obs. focal a numeric vector indicating the focal number in obs. nperm an integer indicating the number of permutations to performed. progress a boolean indicating if the permutation process must be visible. index Which type of index of associations to calculate: 'sri' for Simple ratio index: x \div 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)) measure a character indicating the social network measure to compute (Only those available in ANTs) test a character indicating the test to realize to account for the social network measure df a data frame of individual characteristics in which store permutations. dfid an integer or a string indicating the column with individual ids in argument df. rf an integer (column id) or a string (column name) indicating the column holding the factor grouping multiple networks in argument df. ... Additional arguments related to the social network measure to compute (argument measure).

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