\name{GOenrichment} \alias{GOenrichment} \title{ Searching for Gene Ontology enriched terms within a set of differentially expressed genes } \description{ In Bioconductor is available a library called GOstats, which allows the calculation of enriched GO terms within a set of differentially expressed probe sets. This is a graphical implementation of a function allowing the extraction of GO enriched term in a sub set of differentially expressed probe sets. To know more about it see GOstat library } \usage{ GOenrichment() } \details{ The function asks to the user to select a file containing probe set ids separated by carriage return. The file should contain only one column and no header. The set of enriched terms are plotted in red over the graph of all GO term associated to the differentially expressed genes. GO enriched terms can be also saved in a tab delimited file. } \references{ Robert Gentleman GOstat package} \author{ Raffaele A Calogero } \seealso{extractAffyids, plotGO} \keyword{ methods }
