from_digraph6: Parsing `digraph6` symbols

Description

These functions take a vector of 'digraph6' symbols and return a list of other types of objects:

adjacency_from_digraph6() creates adjacency matrices

igraph_from_digraph6() creates 'igraph' objects. Requires package igraph to be installed.

network_from_digraph6() creates 'network' objects. Requires package network to be installed.

Usage

adjacency_from_digraph6(d6)
igraph_from_digraph6(d6, ...)
network_from_digraph6(d6, ...)

Value

The returned object is:

for adjacency_from_digraph6(), a list of the same length as its input of square symmetric adjacency matrices.

for igraph_from_digraph6(), a list of 'igraph' objects

for network_from_digraph6(), a list of 'network' objects

Arguments

d6: character vector of 'digraph6' symbols
...: other arguments, see Details.

Details

For igraph_from_digraph6() additional arguments are passed to igraph::graph_from_adjacency_matrix()

For network_from_digraph6() additional arguments are passed to network::as.network()

Examples

Run this code

am <- matrix(rbinom(16, 1, 0.3), 4, 4)
d6 <- as_digraph6(am)

# To adjacency matrix ------------------------------------------------------
adjacency_from_digraph6(d6)

# To igraph objects --------------------------------------------------------
if(requireNamespace("igraph", quietly=TRUE)) {
  igraph_from_digraph6(d6)
}

# To network objects -------------------------------------------------------
if(requireNamespace("network", quietly=TRUE)) {
  network_from_digraph6(d6)
}
