Determines whether a graph is set as undirected or not and returns a logical value to that effect.

is_graph_undirected(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a logical value.

Examples

# Create an empty graph; by # default, new graphs made # by `create_graph()` are # directed graph, so, use # `directed = FALSE` to create # an undirected graph graph <- create_graph( directed = FALSE) # Determine whether the # graph is undirected graph %>% is_graph_undirected()
#> [1] TRUE
# Use the `set_graph_directed()` # function and check again # as to whether the graph is # undirected graph %>% set_graph_directed() %>% is_graph_undirected()
#> [1] FALSE
