Add hgnc symbol to expression set.
Function first maps entrez gene ids to homologous human entrez gene ids and then to hgnc symbols.
symbol_annot(eset, gse_name = "")
Expression set to annotate.
GSE name for eset.
Initial entrez gene ids are obtained from bioconductor annotation data packages or from feature data of supplied expression set. Homologous human entrez ids are obtained from homologene and then mapped to hgnc symbols using org.Hs.eg.db. Expression set is expanded if 1:many mappings occur.
Expression set with hgnc symbols ("SYMBOL") and row names ("PROBE") added to fData slot.
