Seth et al, Is there an example somewhere of how to get a list of packages based on one or more biocView tags (programmatically in R)? For example: Given a tag like "hgu133a2", get a matrix like that at: http://www.bioconductor.org/packages/1.8/hgu133a2.html which can then be used to build a list of desired annotation/experiment/etc packages for subsequent install. I was poking around in the new BiocViews package (which I assume is the place to start), but the solution didn't leap out at me. Having the biocView tags is great and I'd love to take full advantage of them. Maybe biocView tags and/or patterns could ultimately be supplied as arguments to getBioC().

Yes, that's the right place to look. This is a feature we discussed, but didn't implement. We wanted to see if the views were useful in general before investing more development effort. What you are asking for makes a lot of sense. > Having the biocView tags is great and I'd love to take full advantage of > them. > > Maybe biocView tags and/or patterns could ultimately be supplied as > arguments to getBioC(). Yep, but stress on "ultimately", or stress on "patches welcome" :-) Here's how you can get a list of the packages in the hgu133a2 view as you mention in the URL in your post. The following is not official, may change in the future, may not work in the first place. But it may solve your problem for the short term. Without further ado... library("biocViews") data(biocViewsVocab) repos <- "http://bioconductor.org/packages/1.8/data/annotation" bv <- getBiocViews(repos, biocViewsVocab, "NoViewProvided") There were 50 or more warnings (use warnings() to see the first 50) > names(bv[["hgu133a2"]]@packageList) [1] "hgu133a2" "hgu133a2cdf" [3] "hgu133a2probe" "hs133av2hsense7cdf" [SNIP] So you could install all of these by passing the result of this to biocLite(). A few notes: * This is _provisional_. I really don't like the direct slot access using "@". * There are three main BioC package repositories that correspond to the three top-level children of the BiocViews root node in the vocabulary: Software, AnnotationData, ExperimentData. The list of views returned by getBiocViews() will contain an entry for _all_ views in the vocabulary, but entries will be empty for views that are not part of the requested repository. Confused? If you wanted to ask about the Software view or one of its subviews, you would need to replace the repos arg with http://bioconductor.org/packages/1.8/bioc. Best, + seth
