Hi,
 
I've output a 'gt.result' in a globaltest analysis of a microarray
experiment. This is a class with a number of slots summarizing the
results of a globaltest on a number of genesets. In this experiment I
tested the association of a number of GO IDs with gene expression. I'd
like to convert these IDs to GO Terms for ease of interpretation.
 
                 Genes Tested Statistic Q Expected Q sd of Q   P-value
FDR.adjusted
GO:0008318     5      5      36.929     5.6901  5.0507 0.0010123

The method to convert KEGG Pathway IDs to KEGG Pathway Names is as
follows (for a 'gt.result' called "top20_k")
 
> names(top20_k) <- as.list(KEGGPATHID2NAME)[names(top20_k)]
 
Is there a similar command to convert GO IDs in this context?
 
Thanks
