compress_same_children: Compress Network by Merging Nodes with Identical Children

In saezlab/COSMOS: COSMOS (Causal Oriented Search of Multi-Omic Space)

Compress Network by Merging Nodes with Identical Children

Description

This function compresses a network by merging nodes that have the same children. The input network is represented as a data frame with three columns: source, target, and sign of interaction. The function returns a list containing the compressed network, node signatures, and duplicated signatures.

Usage

compress_same_children(df, sig_input, metab_input)

Arguments

df	A data frame representing the network with three columns: source, target, and sign of interaction.
sig_input	A list of input node signatures to be considered for the merging process.
metab_input	A list of input metabolic signatures to be considered for the merging process.

Value

A list containing the following elements:

compressed_network	A data frame representing the compressed network.
node_signatures	A list of signatures of nodes in the network after the merging process.
duplicated_signatures	A list of duplicated signatures in the network after the merging process.

Examples

# Create a sample network
df <- data.frame(source = c("A", "A", "B", "B"),
                 target = c("C", "D", "C", "D"),
                 sign_of_interaction = c(1, 1, 1, 1))

# Define input node and metabolic signatures
sig_input <- list()
metab_input <- list()

# Compress the network
result <- compress_same_children(df, sig_input, metab_input)
compressed_network <- result$compressed_network
