gahgu95bENTREZID {gahgu95b} | R Documentation |
gahgu95bENTREZID is an R environment that provides mappings between manufacturer identifiers and Entrez Gene identifiers.
Each manufacturer identifier is mapped to a vector of Entrez Gene identifiers. An
NA
is assigned to those manufacturer identifiers that can not be mapped
to an Entrez Gene identifier at this time.
