Number of parent/child/ancestor/offspring/leaf terms
n_offspring(dag, terms = NULL, use_cache = TRUE, include_self = FALSE)

n_connected_leaves(dag, terms = NULL, use_cache = TRUE)
n_parents(dag, terms = NULL)
n_children(dag, terms = NULL)
avg_parents(dag)
avg_children(dag)An ontology_DAG object.
A vector of term names. If the value is NULL, it returns for all terms in the DAG.
Internally used.
For n_offspring() and n_ancestors(), this controls whether to also include the query term itself.
An integer vector.
For n_connected_leaves(), leaf nodes have value of 1.
In avg_parents(), root term is removed.
In avg_children(), leaf term is removed.
