Aggregate Edge Weights

Aggregates a vector of edge weights using various methods. Compatible with igraph's edge.attr.comb parameter.

Usage

aggregate_weights(w, method = "sum", n_possible = NULL)

wagg(w, method = "sum", n_possible = NULL)

Arguments

w

Numeric vector of edge weights. NA and zero entries are dropped before aggregation.

method

Aggregation method: "sum", "mean", "median", "max", "min", "prod", "density", "geomean". Default "sum". Any other value is an error.

n_possible

Number of possible edges (used only by method = "density"; when NULL or not positive, the number of surviving weights is used as the denominator instead).

Value

A single numeric value, or 0 when no non-zero, non-NA weight remains.

Examples

w <- c(0.5, 0.8, 0.3, 0.9)
aggregate_weights(w, "sum")   # 2.5
#> [1] 2.5
aggregate_weights(w, "mean")  # 0.625
#> [1] 0.625
aggregate_weights(w, "max")   # 0.9
#> [1] 0.9
