agPATH {ag} | R Documentation |
KEGG (Kyoto Encyclopedia of Genes and Genomes) maintains pathway data for various organisms. agPATH maps probe identifiers to the identifiers used by KEGG for pathways in which the genes represented by the probe identifiers are involved
Each KEGG pathway has a name and identifier. Pathway name for a given pathway identifier can be obtained using the KEGG data package that can either be built using AnnBuilder or downloaded from Bioconductor http://www.bioconductor.org.
Graphic presentations of pathways are searchable at url{http://www.genome.ad.jp/kegg/pathway.html} by using pathway identifiers as keys.
