Arguments

A data frame with at least from, to, weight columns.

n

Integer. Number of top nodes to keep.

Value

A filtered data frame with edges among the top n nodes.

Examples

data(biblio_data)
edges <- author_network(biblio_data, "collaboration")

# Keep only edges among the top 3 most connected authors
filter_top(edges, 3)
#> # bibnets network: author_collaboration | 3 nodes · 3 edges | counting: full
