Modifying tie data

These functions allow users to add and delete ties and their attributes:

• add_ties() adds additional ties to network data

• delete_ties() deletes ties from network data

• add_tie_attribute() and mutate_ties() offer ways to add a vector of values to a network as a tie attribute.

• rename_ties() renames tie attributes.

• bind_ties() appends the tie data from two networks and join_ties() merges ties from two networks, adding a tie attribute identifying the newly added ties.

• filter_ties() subsets ties based on some tie attribute-related logical statement.

Note that while add_*()/delete_*() functions operate similarly as comparable {igraph} functions, mutate*(), bind*(), etc work like {tidyverse} or {dplyr}-style functions.

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

ties

The number of ties to be added or an even list of ties.

attribute

A named list to be added as tie or node attributes.

attr_name

Name of the new attribute in the resulting object.

vector

A vector of values for the new attribute.

...

Additional arguments.

object2

A second object to copy nodes or ties from.

Value

A tidygraph (tbl_graph) data object.
