humanCHRLOCENTREZID2CHR {humanCHRLOC}R Documentation

An annotation data file that maps Entrez Gene identifiers to chromosome number

Description

humanCHRLOCENTREZID2CHR maps Entrez Gene identifiers to the chromosome numbers the genes represented by the Locuslink identifiers reside

Details

This is an environment object containing key and value pairs. Keys are Entrez Gene identifiers and values are the corresponding chromosome numbers the genes reside. Values are vectors of length 1 or more depending on whether a give Entrez Gene identifier can be mapped to one or more chromosomes.

Mappings were derived from data provided by:

Examples

        require("annotate") || stop("annotate unavailable")
        xx <- as.list(humanCHRLOCENTREZID2CHR)
        if(length(xx) > 0){
                # Get the value of the first Entrez Gene id
                xx[1]
                # Get the values for a few Entrez Gene identifiers
                if(length(xx) >= 3){
                        xx[1:3]
                }
