Map custom probeset IDs to strand on chromosomes

Description

gahgu95dSTRAND is an R environment that provides mappings between a custom probeset identifier and the strand of gene onto corresponding chromosome.

Details

Each identifier maps to a gene strand. If the gene strand is unknown, the vector will contain an NA.

Mappings were based on data provided by:

Examples

        # Convert to a list
        xx <- as.list(gahgu95dSTRAND)
        # Remove probe identifiers that do not map to any strand
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # Get the base pair number for gene strand for the first five probes
            xx[1:5]
            # Get the first one
            xx[[1]]
        }
