This summer I've written a new package that makes extensive use of the Bioconductor data packages to create annotated HTML and text files. It will take a vector or Affymetrix probe ids and generate a table with quite a bit of useful annotation data. It was mostly inspired by Robert Gentlemen's challenge found in the "ll.htmlpage" documentation: "Details: A simple markup is used to provide clickable entries. Anyone that is energetic could greatly improve this." The usefulness of the package essentially boils down to the function "aaf.summary". For an overview of what the package does, see the documentation for that function. For a quick example, run example(aaf.summary). There may be novel uses for the other functions in the package but they're mainly just slaves to the master function. In this version I haven't officially declared any of the functions private but I think I'll do that at some point soon. annaffy depends on three Bioconductor packages: Biobase (only for the multiget function), GO, and KEGG (for second level annotation). Also, to really be useful for anything, it needs one of the other full annotation data packages available on the Bioconductor web site. I've tested it with the rgu34a package but I haven't gotten around to the other data packages yet. To my knowledge, annaffy is Bioconductor compliant with the exception that I haven't written a vignette yet. It does pass R CMD check. There are most certainly still bugs, typos, and misspellings in the code/documentation. There is one big optimization I know of that still needs to be done. I would greatly appreciate any comments/suggestions/complaints. I haven't implemented functions that handle all the annotation data provided with the annotation packages. I am especially interested in finding out which of the other data sources would be useful and worth implementing. -Colin Source package: http://homepages.nyu.edu/~cas277/annaffy_0.5.tar.gz HTML page produced by example(aaf.summary): http://homepages.nyu.edu/~cas277/affy.html -- Colin Alexander Smith cas277@nyu.edu PGP Public Key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x0B159DFF
