Format Ligand-Receptor Resource — format_LR

This function formats a ligand-receptor resource by creating a gene set with source-target pairs, converting it to a long format, and adding default values for 'mor' and 'likelihood'.

Usage

format_LR_ressource(ligrec_ressource)

Arguments

ligrec_ressource: A data frame representing the ligand-receptor resource with columns for source and target gene symbols.

Value

A data frame containing the formatted ligand-receptor gene set with columns:

gene: The gene symbol from the ligand-receptor pairs.
set: The set identifier combining source and target gene symbols.
mor: Default value set to 1 for all entries.
likelihood: Default value set to 1 for all entries.

Examples

# Create a sample ligand-receptor resource
ligrec_ressource <- data.frame(source_genesymbol = c("L1", "L2"),
                               target_genesymbol = c("R1", "R2"))

# Format the ligand-receptor resource
formatted_geneset <- format_LR_ressource(ligrec_ressource)
