Before you spend the time and effort to building an annotation package, you might simply download the annotation file from Affy and do things 'by hand'. http://www.affymetrix.com/Auth/analysis/downloads/taf/Celegans_annot_c sv.zip You can import this file into R using read.csv(), and then annotate your list of significant genes. You can use htmlpage() in the annotate package to output an HTML table with links to various online databases (see the prettyOutput vignette).
