## Map Open Reading Frame (ORF) Identifiers to Alias Gene Names

### Description

A set of gene names may have been used to report yeast genes represented by ORF identifiers. One of these names is chosen to be the primary gene name, and the others are considered aliases. This R object provides mappings between the primary name and aliases.

### Details

Each primary name maps to a vector of alias names. If there are no aliases, the vector will contain `NA`.

### Examples

        x <- yeast2ALIAS
        # Get the probe identifiers that are mapped to alias names
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
            # Get the alias names for the first five probes
            xx[1:5]
            # For the first probe
            xx[[1]]
        }
