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)

Arguments

graph

a graph object of class dgr_graph.

agg

the aggregation function to use for summarizing indegree values from graph nodes. The following aggregation functions can be used: sum, min, max, mean, or median.

conditions

an option to use filtering conditions for the nodes to consider.

Value

a vector with an aggregate indegree value.

Examples

# Create a random graph using the # `add_gnm_graph()` function graph <- create_graph() %>% add_gnm_graph( n = 20, m = 35, set_seed = 23) %>% set_node_attrs( node_attr = value, values = rnorm( n = count_nodes(.), mean = 5, sd = 1) %>% round(1)) # Get the mean indegree value # from all nodes in the graph graph %>% get_agg_degree_in( agg = "mean")
#> [1] 1.75
# 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")
#> [1] 1.5
# The aggregation of indegree # can occur for a subset of the # graph nodes and this is made # possible by specifying # `conditions` for the nodes graph %>% get_agg_degree_in( agg = "mean", conditions = value > 5.0)
#> [1] 1.5
