from_graph6 function

Functions parsing 'graph6' symbols

These functions take a vector of 'graph6' symbols and return a list of other types of objects:

• adjacency_from_graph6() creates adjacency matrices

• igraph_from_graph6() creates 'igraph' objects. Requires package igraph to be installed.

• network_from_graph6() creates network objects. Requires package network to be installed.

adjacency_from_graph6(g6)

igraph_from_graph6(g6, ...)

network_from_graph6(g6, ...)

Arguments

• g6: character vector of 'graph6' symbols
• ...: other arguments, see Details.

Returns

The returned object is:

• for adjacency_from_graph6(), a list of the same length as its input of square symmetric adjacency matrices.

• for igraph_from_graph6(), a list of 'igraph' objects

• for network_from_graph6(), a list of network objects

Details

For igraph_from_graph6() additional arguments are passed to igraph::graph_from_adjacency_matrix()

For network_from_graph6() additional arguments are passed to network::as.network()

Examples

A <- matrix(c(0,1,0,1,
              1,0,1,0,
              0,1,0,1,
              1,0,1,0), 4, 4, byrow = TRUE)
g6 <- as_graph6(A)

# To adjacency matrix ------------------------------------------------------
adjacency_from_graph6(g6)

# To igraph objects --------------------------------------------------------
if(requireNamespace("igraph", quietly=TRUE)) {
  igraph_from_graph6(g6)
}

# To network objects -------------------------------------------------------
if(requireNamespace("network", quietly=TRUE)) {
  network_from_graph6(g6)
}
