A new minor release RQuantLib 0.3.10 is now on CRAN and in Debian. RQuantLib combines (some of) the quantitative analytics of QuantLib with the R statistical computing environment and language. The discount curve building code in QuantLib has s... [Read more...]

digest version 0.6.3 is now on CRAN, and I'll upload the Debian package in a minute. This is a minor bug release regarding just the recently-added sha512 support. Turns out the wrong initial buffer size was used on the R side. Hannes fixed that with... [Read more...]

Some little birds had already been whispering about it, but I didn't want to jinx it and told myself I would wait with an announcement until the booksellers have (at least) placeholder pages. And as I learned from Duncan Murdoch via email earlier toda... [Read more...]

Lots of exciting things are happening with and around Rcpp. I just added a new page about Upcoming Events to the recently-created Rcpp site. This events page has lots to cover: an upcoming talk at Columbia on March 8 (details still TBD), a day-lon... [Read more...]

A good three weeks ago, we introduced the Rcpp Gallery. While this is a joint effort by several of us on the Rcpp team, the backend was conceived and implemented entirely by JJ who also bootstrapped it with same first content, drawing on posts by Ha... [Read more...]

A pure maintenance release 0.1.6 of RcppExamples was made two weeks ago, and never announced. We merely moved the NEWS.Rd file into the proper location in the inst/ directory, and, while were at it, mentioned the new Rcpp Gallery in the DESCRIPTION fi... [Read more...]

digest version 0.6.2 came out a few days ago as an almost immediate follow-up to release 0.6.1. We used paste0() in a few places, and this is only available with newer versions of R. To not introduce as somewhat unnessecary dependency, we reverted thi... [Read more...]

Earlier today a new package BH arrived on CRAN. Over the years, Jay Emerson, Michael Kane and I had numerous discussions about a basic Boost infrastructure package providing Boost headers for other CRAN packages (and yes, we are talking packages usin... [Read more...]

With the arrival earlier today of the stochvol package onto the CRAN network for R, our Rcpp project reached a new milestone: 100 packages have either a Depends:, Imports: or LinkingTo: statement on it. The full list will always be at the bottom of ... [Read more...]

digest version 0.6.1 is now on CRAN, and I will push the corresponding version into Debian shortly. Duncan Murdoch added AES support, and helped me fix two issues which (annoyingly) made the Rout.save output differ on another platform. CRANberries... [Read more...]

Earlier this morning, JJ announced what we had been working on for the last few weeks: the Rcpp Gallery. Now, as our luck will have it, the Rcpp-devel list received his message but did not transmit it for an apparent mail system outage at WU Vienna:... [Read more...]

Yesterday's initial upload of RcppClassicExamples was lacking a versioned Depends: to prevent builds on older versions of R. This has been added in a new upload 0.1.1. We also added a NEWS file (see below); no code changes were made. Changes in ver... [Read more...]

The recent releases of Rcpp 0.10.2 and RcppClassic 0.9.3 had one more repercussion. On that dreaded OS, the linker no longer wanted to instantiate a symbol present in both packages; seems to me that the linker in the other two OSs is a little smarter... [Read more...]

Yesterday's release of Rcpp 0.10.2 required a small change to RcppClassic, the package supporting the deprecated older classic Rcpp API defined in the earlier 2005 to 2006 releases. So version 0.9.3 of RcppClassic is now on CRAN. There is no new user... [Read more...]

Relase 0.10.2 of Rcpp provides the second update to the 0.10.* series, and has arrived on CRAN and in Debian. It brings another great set of enhancements and extensions, building on the recent 0.10.0 and 0.10.1 releases. The new Rcpp attributes were rewritten to not require Rcpp modules (as we encountered on issue with ... [Read more...]

Following the Rcpp 0.10.0 release, I had written about simulating pi easily by using the wonderful new Rcpp Attributes feature. Now with Rcpp 0.10.1 released a good week ago, it is time to look at how Rcpp Attributes can help with external libraries. As this posts aims to show, it is a ... [Read more...]
