These functions creates a long list of different types of well-defined graphs, that is, their structure is not based on any randomisation. All of these functions are shallow wrappers around a range of igraph::make_* functions but returns tbl_graph rather than igraph objects.

create_tree(n, children, directed = TRUE, mode = "out")

## Arguments

n, n1, n2 The number of nodes in the graph Should the graph be directed Should mutual edges be created in case of the graph being directed A matrix specifying the additional edges in the chordan ring. See igraph::make_chordal_ring() The number of unique letters in the alphabet used for the graph The number of characters in each node In case of a directed, non-mutual, graph should the edges flow 'out' or 'in' The name of a notable graph. See a complete list in igraph::make_graph() The dimensions of the lattice Should each dimension in the lattice wrap around The number of children each node has in the tree (if possible)

A tbl_graph
