node_harmonic(.data, normalized = TRUE, k = -1)
tie_closeness(.data, normalized = TRUE)

network_harmonic(.data, normalized = TRUE, k = 2)
.data |
An object of a
|
normalized |
Logical scalar, whether the centrality scores are normalized. Different denominators are used depending on whether the object is one-mode or two-mode, the type of centrality, and other arguments. |
direction |
Character string, “out” bases the measure on outgoing ties, “in” on incoming ties, and "all" on either/the sum of the two. For two-mode networks, "all" uses as numerator the sum of differences between the maximum centrality score for the mode against all other centrality scores in the network, whereas "in" uses as numerator the sum of differences between the maximum centrality score for the mode against only the centrality scores of the other nodes in that mode. |
cutoff |
Maximum path length to use during calculations. |
k |
Integer of steps out to calculate reach |
node_closeness()
: Calculate the closeness centrality of nodes in a network
node_reach()
: Calculate nodes' reach centrality
or how many nodes they can reach within k steps
node_harmonic()
: Calculate nodes' harmonic centrality or valued centrality.
This is thought to behave better than reach centrality for disconnected networks.
tie_closeness()
: Calculate the closeness of each edge to each other edge
in the network.
network_closeness()
: Calculate a network's closeness centralization
network_reach()
: Calculate a network's reach centralization
network_harmonic()
: Calculate a network's harmonic centralization
