EMG Coordination Structure Summary from Network Topology

Source: R/emg-network.R
emgCoordinationStructure.Rd

Quantifies higher-order muscle coordination structure from a weighted network matrix, including module structure, efficiency, and node roles.

Usage

emgCoordinationStructure(
  network,
  threshold = NULL,
  n_modules = NULL,
  max_modules = 6L,
  directed = FALSE,
  symmetrize = c("mean", "max", "min"),
  normalize = TRUE
)

Arguments

network

Numeric square matrix (channels x channels) or a list containing $network.

threshold

Optional edge-weight threshold. Values below threshold are set to zero before topology estimation.

n_modules

Optional number of modules. If NULL, chooses a value automatically by maximizing weighted modularity over candidates.

max_modules

Maximum number of candidate modules for automatic search.

directed

Logical; set TRUE if network is directed/asymmetric.

symmetrize

Method to convert directed matrices to undirected form: "mean", "max", or "min".

normalize

Logical; if TRUE, rescales weights to [0, 1].

Value

A list with:

network

Processed undirected weighted network matrix.

node_metrics

Data.frame of node-level topology features.

modules

Named integer vector of module assignments.

summary

Global network topology summary.
