Creating (small) graphs via a simple interface

graph.formula() was renamed to graph_from_literal() to create a more consistent API.

graph.formula(..., simplify = TRUE)

Arguments

...

For graph_from_literal() the formulae giving the structure of the graph, see details below. For from_literal() all arguments are passed to graph_from_literal().

simplify

Logical scalar, whether to call simplify() on the created graph. By default the graph is simplified, loop and multiple edges are removed.
