Register a Network Estimator

Description

Register a custom or built-in network estimator function by name. Estimators registered here can be used by estimate_network via the method parameter.

Usage

register_estimator(name, fn, description, directed)

Arguments

name	Character. Unique name for the estimator (e.g. "relative", "glasso").
fn	Function. The estimator function. Must accept data as its first argument and ... for additional parameters. Must return a list with at least: matrix (square numeric matrix), nodes (character vector), directed (logical).
description	Character. Short description of the estimator.
directed	Logical. Whether the estimator produces directed networks.

my_fn <- function(data, ...) {
  m <- cor(data)
  diag(m) <- 0
  list(matrix = m, nodes = colnames(m), directed = FALSE)
}
register_estimator("my_cor", my_fn, "Custom correlation", directed = FALSE)
df <- data.frame(A = rnorm(20), B = rnorm(20), C = rnorm(20))
net <- build_network(df, method = "my_cor")
remove_estimator("my_cor")
