Hi Steven, I am the GSOC student in question and I think the best statement of work is probably this one here on the GSOC-R Wiki (as well as for the other projects):
http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2012:xts If you log into Google Melange, my project proposal should publicly visible and has a bit more detail on the scope of the project, but not much more than the wiki has so it's probably not worth the work of setting up an account. If this is of interest to you, I'd invite you to follow my work on R-Forge: http://r-forge.r-project.org/projects/xts/ My work is currently in the xtsExtra package and will be moved into xts (regular) once it's been thoroughly tested. The only thing currently in it is a new take on plot.xts which should be much more flexible as regards multivariate series, but things are changing quickly. If you have a features you'd like to see added, please don't hesitate to drop me an email and we can chat about them -- there's a pretty good to do list in place already, but it can never hurt to see where the community's interest lies.
