yeast2ORF {yeast2.db} | R Documentation |
yeast2ORF is an R object that provides mappings between manufacturer and ORF identifiers.
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.
