get_agg_degree_in {DiagrammeR} | R Documentation |
Get a single, aggregate value from the indegree values for all nodes in a graph, or, a subset of graph nodes.
get_agg_degree_in(graph, agg, conditions = NULL)
graph |
a graph object of
class |
agg |
the aggregation
function to use for summarizing
indegree values from graph nodes.
The following aggregation functions
can be used: |
conditions |
an option to use filtering conditions for the nodes to consider. |
a vector with an aggregate indegree value.
