R: Data linking genes and pathways.

genes {ggparallel} | R Documentation

## Data linking genes and pathways.

### Description

Table knownGene from track UCSC Genes was downloaded from the UCSC table browser for the human genome assembly (hg18, May 2006) and filtered for a selection of pathways associated with human metabolism was obtained from KEGG PATHWAY database. Bioconductor package KEGG.db was used to provide mappings between gene and pathway identifiers.

### Usage

    genes

### Format

An object of class `data.frame` with 2768 rows and 14 columns.
