\begin{Description}\relax
drosophila2GO2PROBE is an R environment that provides mappings between
GO identifiers and manufacturer identifiers.
\end{Description}
\begin{Details}\relax
Each GO term maps to a named vector of manufacturer identifiers. The name
associated with each manufacturer identifier corresponds to the evidence code
for that GO identifier. The evidence code indicates what kind of evidence
supports the association between the GO and Entrez Gene identifiers. Evidence
codes currently in use include:

IMP - inferred from mutant phenotype

IGI - inferred from genetic interaction

IPI - inferred from physical interaction  

ISS - inferred from sequence similarity  

IDA - inferred from direct assay  

IEP - inferred from expression pattern  

IEA - inferred from electronic annotation  

TAS - traceable author statement  

NAS - non-traceable author statement  

ND - no biological data available  

IC - inferred by curator

A GO identifier may be mapped to the same probe identifier more than once but
the evidence code can be different. Mappings between Gene Ontology identifiers
an Gene Ontology terms and other information are available in a
separate data package named GO. 

Mappings were based on data provided by:

\begin{Examples}
\begin{ExampleCode}
    # Convert to a list
    xx <- as.list(drosophila2GO2PROBE)
    if(length(xx) > 0){
        # Gets the probe identifiers for the top 2nd and 3nd GO identifiers
        goids <- xx[2:3]
        # Gets the probe identifiers for the first element of goids
        goids[[1]]
        # Evidence code for the mappings
        names(goids[[1]])
    }
