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
- method
Aggregation method: "sum", "mean", "median", "max", "min",
"prod", "density", "geomean"
- n_possible
Number of possible edges (for density calculation)
Value
Single aggregated value
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
# \donttest{
mat <- matrix(c(0, 0.5, 0.5, 0.3, 0, 0.7, 0.4, 0.6, 0), 3, 3, byrow = TRUE)
aggregate_weights(mat)
#> [1] 3
# }
