I have in fact handed a complete draft of my book about Seamless R and C++ Integration with Rcpp to Springer a few weeks ago. With a bit of luck on the production side, we could be seeing physical copies by May of a new title in their popular UseR! Series series.
And to the slowly growing new Rcpp site, I have added a a formal page about the Rcpp book where one can find information about it, including a link to the Springer page, links to a few bookseller's pages --- as well as a few wonderfully flattering endorsements. Eventually, errata and other support material should be available via this page too. Can't wait til I hold a physical copy in hand...
With that, a few quick words about the upcoming master class in New York. It will be a full day, covering an introduction and motivation, details about the core data types, tools for working with and and extending Rcpp and of course applications galore, including RcppArmadillo and RInside. I have done the same one day class format a few times before, most recently (with Revolution Analytics) in San Francisco in late 2011, and also as a two-part seminar at UseR! 2012. This time, we plan on providing cloud-hosted RStudio instances for participants. Better still, RStudio's own JJ Allaire will be on deck as well for RStudio --- and Rcpp Attributes --- questions.
Details and registration information for the New York class are at this page.
