Create components

Description

This function creates network components (connected subgraphs) from edge lists using igraph. Each component represents a set of features that are connected through spectral similarity or other relationships.

Usage

create_components(
  input = get_params(step = "create_components")\$files\$networks\$spectral\$edges\$prepared,
  output = get_params(step = "create_components")\$files\$networks\$spectral\$components\$raw
)

Arguments

input	Character vector of file path(s) containing edge data. Files should have feature_source and feature_target columns.
output	Character string path for the output components file

Value

Character string path to the created components file
