agSYMBOL {ag} | R Documentation |
agSYMBOL is an R environment that provides mappings between manufacturer identifiers and gene abbreviations.
Each manufacturer identifier is mapped to an abbreviation for the
corresponding gene. An NA
is reported if there is no known
abbreviation for a given gene.
Symbols typically consist of 3 letters that define either a single gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can be used as key words to query public databases such as Entrez Gene.
Mappings were based on data provided by:
