Well @joshua_ulrich it's a free country, so pick anything with or without 'Rcpp sugar' from the menu. But 'Rcpp attributes' help digest.

New Rcpp 0.10.1 with more attributes, sugar, modules goodness; breakage in RcppEigen + RcppOctave, see goo.gl/fPPyX #rstats #rcpp

MT @lgatt0 @eddelbuettel Showed pi estimation example with Rcpp attributes during an #rstats devel class today - people were impressed!
Awesome: Define H away from HFT, then conclude Java wins over C++. MT @QuantBlogs C++ or Java, which is faster HFT? bit.ly/10Xtm1s

New version 0.6.0 of our digest package, now with sha512 thanks to @hfmuehleisen, more at goo.gl/5PR4A #rstats

Bill is in the mail MT @ProbablePattern When I have problems w/ #rstats + #ubuntu I usually find the solution in comment by @eddelbuettel

@hadleywickham I've been using both for years. Last post didn't really need either though, benchmark'ed just for completeness.
@hadleywickham The Edmund Hillary response: "Because it is there". rbenchmark was first, microbenchmark came later. #rstats

Absolutely -- thanks for catching that. Fixed. MT @shabbychef: in the example code, shouldn't it be resCpp <- piSugar(N) ?

"Making pi": a small simulation to show just how easy adding C++ to R now is thanks to Rcpp attributes goo.gl/Kzl94 #rstats #rcpp

@jaredlander One of the reasons RPostgreSQL rocks is that even on Windows it just works (via code in pkg; on Linux system libs used)
@hadleywickham Are you missing the underscores or are the 2s in the wrong places? #couldNotResistThisLayup
@hadleywickham That is Init, test, body, incr, test, body, incr, test --- seems perfectly fine to me.

@revodavid @HarlanH @jeffreyhorner: RPostgreSQL found a pot of gold in Tomoaki who is simply amazing as the current maintainer. #rstats

@theCanadaParty Or how about if we fuse Texas and Alberta and leave the rest of us in peace?
@jcborras @revodavid Yes, the sum of R and C++ gives you more than the parts: wouldn't want C++ without R, or R without C++. #rstats #rcpp
RcppArmadillo 0.3.4.4 release with minor upstream changes, more at goo.gl/p7mdM #rstats
