Getting to know the data is always an interesting part of data science. With R integration into SQL Server, the exploration part is still part of the game. Usual way to get some statistics out of the dataset is to run some frequencies, descriptive statistics and nevertheless correlations. Running correlations ...

I’ve released a new version of my pqR implementation of R. This version introduces extensions to the R language that fix some long-standing design flaws that were inherited from S. These language extensions make it easier to write reliable programs, that work even in edge cases, such as data ...

Introduction A while back I saw a post on StackOverflow where the user was trying to use Rcpp::sugar::sum() on an RcppParallel::RVector. Obviously this doesn’t work and it raised the question “Why doesn’t something more generic exist to provide functions with R semantics that can be ...

Introduction Consider a need to be able to interface with a data type that is not presently supported by Rcpp. The data type might come from a new library or from within ones own program. In such cases, Rcpp is faced with an issue of consciousness as the new data ...

If you had asked me two years ago if Microsoft was a serious vendor for data science and analytics infrastructure and tools, I would have laughed. At the time their offering seemed to me to consist of Excel against SQL Server. There is nothing really wrong (or exciting) about SQL ...

Introduction My 5-qubit Quantum Computing Simulator,QCSimulator, is finally ready, and here it is! I have been able to successfully complete this simulator by working through a fair amount of material. To a large extent, the simulator is easy, if one understands how to solve the quantum circuit. However the ...
