## Map between custom probeset Identifiers and Entrez Gene

### Description

gahgu95cENTREZID is an R environment that provides mappings between manufacturer identifiers and Entrez Gene identifiers.

### Examples

        # Convert the environment to a list
        xx <- as.list(gahgu95cENTREZID)
        # Remove probe identifiers that do not map to any ENTREZID
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # The ENTREZIDs for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
