manip_ties function

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.

add_ties(.data, ties, attribute = NULL)

delete_ties(.data, ties)

add_tie_attribute(.data, attr_name, vector)

mutate_ties(.data, ...)

rename_ties(.data, ...)

arrange_ties(.data, ...)

bind_ties(.data, ...)

join_ties(.data, object2, attr_name)

filter_ties(.data, ...)

select_ties(.data, ...)

summarise_ties(.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

• 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.

Returns

A tidygraph (tbl_graph) data object.

Examples

other <- create_filled(4) %>% mutate(name = c("A", "B", "C", "D"))
  mutate_ties(other, form = 1:6) %>% filter_ties(form < 4)
  add_tie_attribute(other, "weight", c(1, 2, 2, 2, 1, 2))
ison_adolescents %>% add_ties(c("Betty","Tina")) %>% graphr()
delete_ties(ison_adolescents, 3)
delete_ties(ison_adolescents, "Alice|Sue")
