path_enrich {famat} | R Documentation

## Pathway enrichment analysis

### Description

Perform a pathway enrichment analysis using a list of genes and a list of metabolites. Pathways enrichment analysis is performed using MPINet for metabolites and gprofiler2 for genes.

### Usage

        path_enrich(source, metabo, genes)

### Arguments

`source` | Pathways database used, either Kegg ("KEGG"), Reactome ("REAC") or Wikipathays ("WP")
`metabo` | Dataframe with three columns : the first column contain the list of metabolites, the second some quantitative data about the metabolites, the last one words "DOWN" or "UP" depending on the metabolites concentration behavior in a certain condition. Last two columns can contain only/some NAs. All metabolites ids are KEGG Compound ids.
`genes` | Dataframe with three columns : the first column contain the list of genes, the second some quantitative data about the genes, the last one words "DOWN" or "UP" depending on the genes expression behavior in a certain condition. Last two columns can contain only/some NAs. All genes ids are gene symbol.

### Value

A list containing :

`resmeta` | Results of metabolites pathway enrichment analysis
`resgene` | Results of genes pathway enrichment analysis
`genes` | Vector containing genes
`metabo` | Vector containing metabolites

This list is used by `interactions` function.
