Modifying network levels

Source: R/modif_levels.R

These functions reformat the levels in manynet-consistent network data.

  • to_onemode() reformats two-mode network data into one-mode network data by simply removing the nodeset 'type' information. Note that this is not the same as to_mode1() or to_mode2().

  • to_twomode() reformats one-mode network data into two-mode network data, using a mark to distinguish the two sets of nodes.

  • to_multilevel() reformats two-mode network data into multimodal network data, which allows for more levels and ties within modes.

If the format condition is not met, for example to_onemode() is used on a network that is already one-mode, the network data is returned unaltered. No warning is given so that these functions can be used to ensure conformance.

Unlike the as_*() group of functions, these functions always return the same class as they are given, only transforming these objects' properties.

to_onemode(.data)

to_twomode(.data, mark)

to_multilevel(.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

mark

A logical vector marking two types or modes. By default "type".

Value

A tidygraph object modified as explained in the function description, details, or section.

Not all functions have methods available for all object classes. Below are the currently implemented S3 methods:
