Get an aggregate value from the indegree of nodes
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.
# Create a random graph using the
# `add_gnm_graph()` function

sd = 1) %>% round(1))
# Get the mean indegree value
# from all nodes in the graph
graph %>%
get_agg_degree_in(
agg = "mean")
# Other aggregation functions
# can be used (`min`, `max`,
# `median`, `sum`); let's get
# the median in this example
graph %>%
get_agg_degree_in(
agg = "median")
# The aggregation of indegree
# can occur for a subset of the
# graph nodes and this is made
# possible by specifying
# `conditions` for the nodes
