org.Rn.egMAP {org.Rn.eg.db} | R Documentation |
org.Rn.egMAP is an R object that provides mappings between entrez gene identifiers and cytoband locations.
Each entrez gene identifier is mapped to a vector of cytoband locations. The
vector length may be one or longer, if there are multiple reported
chromosomal locations for a given gene. An NA
is reported for
any entrez gene identifiers that cannot be mapped to a cytoband at this time.
Mappings were based on data provided by: Entrez Gene ftp://ftp.ncbi.nlm.nih.gov/gene/DATA With a date stamp from the source of: 2011-Sep14
