A reasonably straightforward post today. I wanted to look at monthly tourism numbers in Samoa. In fact I started to do this for Pacific islands in general, but the data wrangling challenges were sufficient that I only got as far as Samoa for now. There...

If you are reading this post on R-bloggers, you will probably know that I have been publishing my selection of the “Top 40” new R packages on CRAN for quite some time. I did this first as part of my work at Revolution Analytics, then on R Views ...

You probably call them all "mock". What each type of test double actually is, when to reach for it in R, and what goes wrong when you mix them up.

Stanislaw Ulam, Los Alamos, 1963 was bored in a meeting and he started dooddling integers in a spiral and circled the primes. Diagonal lines appeared. He later showed it to Martin Gardner, to Ulam surprise, Gardner published his findings in…Read more ›

🧬 Back to basics! Learning non-polar amino acids, what zwitterions actually are, and dipping into the applied math — Rodrigues rotation and Lennard-Jones potential. Slowly building toward optimal phi/psi! Motivations We’ve explored quite a bit lately in molecular dynamic simulation and then protein-protein docking as well the last time. There ...

One of the challenges of working on R-universe is that there is never really a release day. Unlike software projects that accumulate changes for a big launch, R-universe evolves continuously. New features, infrastructure improvements, UI tweaks, and b...

1. Introduction & Theoretical Framework In modern electronic trading markets, algorithmic execution engines drive the vast majority of institutional order flows. Evaluating whether these independent, learning-driven trading algorithms behave competitively or tacitly coordinate has become a critical challenge for quantitative compliance, market microstructure design, and risk management. This technical article implements an ...

Learn to recognize problems in R test code that cause your test suite to pass while hiding real bugs. Detect those issues and start writing more trustworthy tests.

Three hundred seventy-six of the new packages submitted to CRAN in April were still there in mid-May. Here are my Top 40 picks in twenty-three categories: Actuarial Analysis, Archaeology, Biology, Causal Inference, Computational Methods, Ecology...
