rewireCpp {clustAnalytics}

Randomizes a weighted graph while keeping the degree distribution constant.

Description

Converts the graph to a weighted edge list in NumericMatrix, which is compatible with Rcpp. The Rcpp function "randomize" is called, and then the resulting edge list is converted back into an igraph object.

Usage

rewireCpp(
  g,
  Q = 100,
  weight_sel = "max_weight",
  lower_bound = 0,
  upper_bound = NULL
)

Arguments

g

igraph graph, which can be weighted.

Q

Numeric. Parameter that controls the number of iterations, which will be Q times the order of the graph.

weight_sel

can be either "const_var" or "max_weight".

lower_bound, upper_bound

Bounds to the edge weights. The randomization process will avoid steps that would make edge weights fall outside these bounds. Set to NULL for no bound. By default, 0 and NULL respectively.

Value

The rewired graph.
