subsampled_network_metrics function

To generate subsamples and obtain network metrics of the subsamples

subsampled_network_metrics(
  network,
  n_simulations = 100,
  subsampling_proportion = c(0.1, 0.3, 0.5, 0.7, 0.9),
  network_metrics_functions_list = c(edge_density = function(x) igraph::edge_density(x),
    diameter = function(x) igraph::diameter(x, weights = NA), transitivity = function(x)
    igraph::transitivity(x))
)

Arguments

• network: An igraph graph object consisting of observed network
• n_simulations: Number of sub-samples to be obtained at each level
• subsampling_proportion: A vector depicting the levels (in proportion) at which subsamples to be taken
• network_metrics_functions_list: A list consisting of function definitions of the network metrics that the user wants to evaluate. Each element in the list should have an assigned name. Default = c("edge_density" = function(x) igraph::edge_density(x), "diameter" = function(x) igraph::diameter(x, weights = NA), "transitivity" = function(x) igraph::transitivity(x))

Returns

A list of network metrics of class "Subsampled_Network_Metrics". Each element of list is a matrix whose columns correspond to subsampling_proportion and rows correspond to n_simulations. The entries of the matrix provide values of the corresponding metric.

Examples

data(elk_network_2010)
elk_subsamples <- subsampled_network_metrics(elk_network_2010)
plot(elk_subsamples, elk_network_2010, 
network_metrics_functions_list = c("edge_density" = function(x) igraph::edge_density(x),
"diameter" = function(x) igraph::diameter(x, weights = NA),
"transitivity" = function(x) igraph::transitivity(x)))
