## Map Manufacturer Identifiers to Open Reading Frame (ORF) Identifiers

### Description

yeast2ORF is an R object that provides mappings between manufacturer and ORF identifiers.

### Details

Each manufacturer identifier is mapped to a vector of ORF identifiers. The length of the vector may be one or longer, depending on how many ORF identifiers the manufacturer identifier can be mapped to. An `NA` is reported for any manufacturer identifier that cannot be mapped to an ORF identifier at this time.

### Examples

            x <- yeast2ORF
            # Get the probe identifiers that are mapped to ORF identifiers
            mapped_probes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_probes])
            if(length(xx) > 0) {
              # Get the ORF identifiers for the first five probes
              xx[1:5]
              # For the first probe
              xx[[1]]
            }
