WebJul 7, 2024 · The tbl_graph object. Underneath the hood of tidygraph lies the well-oiled machinery of igraph, ensuring efficient graph manipulation. Rather than keeping the node and edge data in a list and creating igraph objects on the fly when needed, tidygraph subclasses igraph with the tbl_graph class and simply exposes it in a tidy manner. This … WebThe way it filters the vertices depends on its positional and keyword arguments. Positional arguments (the ones without an explicit name like _degree above) are always processed before keyword arguments as follows: If the first positional argument is None, an empty sequence (containing no vertices) is returned:
