I've been doing R/Java development for some time, creating packages both large and small with this tool chain. I have used Eclipse as my package development environment almost exclusively, but I didn't realize how much I relied on the IDE before I had to do some serious R/C++ package development. My first Rcpp package (wordcloud)
In my previous post, I tried to show, that Rcpp is 1000 faster than pure R and that generated the fuss in the comments. Being lazy, I didn’t vectorize R code and at the end I was comparing apples vs oranges. To fix that problem, I built a new script, where I’m trying to compare
While ago I built two R scripts to track OMX Baltic Benchmark Fund against the index. One script returns the deviation of fund from the index and it works fast enough. The second calculates the value of the fund every minute and it used to take for while. For example, it spent 2 minutes or
I'll present Rcpp at the inaugural Geneva-R meeting. Geneva-R is an informal gathering of R enthusiasts sponsored by Mango Solutions, that builds on the success of London-R, where I presented twice, and Basel-R
I pushed highlight 0.2-5 on CRAN. This release improves the latex renderer and the sweave driver so that multiple lines character strings are properly rendered.
This example vignette shows it:

We released the first version of our RcppGSL package. RcppGSL extends Rcpp to help programmers code with the GNU Scientific Library (GSL). The package contains template classes in the RcppGSL namespace that act as smart pointers to the associat...
I've pushed a new version of the parser package to CRAN. This is the first release that depends on Rcpp, which allowed me to reduce the code size and increase its maintainability. This also features a faster version of nlines, a function that r...
Rcpp 0.8.9 was pushed to CRAN recently. Apart from minor bug fixes, this release concentrates on modules, with lots of new features to expose C++ functions and classes through R reference classes. The Rcpp-modules vignette has all the details, a...
Following this post, the 90 minutes presentation is now available to watch on youtube:
Last stop on my World tour was Google headquarters in Mountain View, California, where Dirk and I presented Rcpp, RInside, RProtoBuf, etc ... for 90 minutes today. The talk was recorded, and will be broadcasted on youtube at some point. In the mean...
