perm.ds.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.ds.focal(
df,
focal,
ctrl = NULL,
alters,
nperm,
progress = T,
index = "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. index 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.
