miss {manynet}

Modifying missing tie data

Description

These functions offer tools for imputing missing tie data. Currently two options are available:

• na_to_zero() replaces any missing values with zeros, which are the modal value in sparse social networks.

• na_to_mean() replaces missing values with the average non-missing value.

Usage

na_to_zero(.data)

na_to_mean(.data)

Arguments

.data

An object of a manynet-consistent class:

• matrix (adjacency or incidence) from {base} R

• edgelist, a data frame from {base} R or tibble from {tibble}

• igraph, from the {igraph} package

• network, from the {network} package

• tbl_graph, from the {tidygraph} package

Value

A data object of the same class as the function was given.
