This page is automagically updated when I do a periodic full rebuild of the phyloseq extensions documentation. The date of this particular re-build is Sat Feb 15 10:54:23 2014.
Don't forget to checkout the phyloseq demo repository for other tutorials; some more in-depth or lengthy than are maintained here, where the focus is documenting phyloseq extension functionality rather than demonstrating use cases with new/large datasets.
For more advanced users interested in seeing and/or modifying the R markdown source code from which these reproducible, web browser-friendly tutorials were created.
