met.reach: Reach centrality

In SebastianSosa/ant: Animal Network Toolkit Software

Reach centrality

Description

Calculates the weighted node metric 'reach centrality' for all vertices.

Usage

met.reach(M, df = NULL, dfid = NULL)

Arguments

M	a square adjacency matrix, or a list of square adjacency matrices, or an output of ANT functions stat.ds.grp, stat.df.focal, stat.net.lk.
df	a data frame of same length as the input matrix or a list of data frames if argument M is a list of matrices or an output of ANT functions stat.ds.grp, stat.df.focal, stat.net.lk.
dfid	an integer or a string indicating the column with individual ids in argument df.

Details

Reach is the sum of the product of ego's and alters' strengths and alters' degrees.

Value

• An integer vector of nodes reach centrality if argument df is NULL.

• A list of integer vectors of nodes reach centrality if argument M is a list of matrices and if argument df is NULL.

• A list of arguments df with a new column for nodes reach centrality titled 'reach centrality', if argument df is not NULL.

• A list of arguments df with a new column for nodes reach centrality if 1) argument df is not NULL, 2) argument M is an output from ANT functions stat.ds.grp, stat.df.focal, stat.net.lk for multiple matrices permutations, and 3) argument df is a list of data frames of same length as argument M. The name of the column of each element of the list is adapted according to argument value binary.
