{talib} is a new R package built on TA-Lib, which is now available on CRAN. The R-package is targeted at individuals and, perhaps, institutions who, in some form or the other, interacts with the financial markets using technical analysis. The library is built with minimal dependencies for long-term stability and ...

TheseusPlot is an R package that decomposes differences in a rate metric between two groups into subgroup-level contributions and visualizes the results as a “Theseus Plot”. For example, when a click-through rate, conversion rate, or retention r...

My client's supervisor had rejected Chapter 4 twice. Not because the data was bad — the field trial was clean, the yield measurements precise. The problem was the statistics. And until I looked at the file, the student had no idea what was actually wro...

Introduction: The Laboratorial Illusion In quantitative finance, Large Language Model (LLM) multi-agent systems are frequently celebrated for their theoretical intelligence. Financial data scientists spend months refining prompt semantics, building complex reasoning frameworks, and engineering multi-turn debate loops between specialized agent nodes. On paper—and within simulated environments—these networks demonstrate ...

A Bioconductor-centric hackathon dedicated to spatial omics was organized by members of the Bioconductor community – Davide Risso (University of Padua, Italy), Helena Crowell (CNAG Barcelona, Spain), and Wolfgang Huber (EMBL) – on 19-22 April on...

Introduction Bioconductor policies include being an active and reachable maintainer. Maintainer emails in the DESCRIPTION of packages often go stale as maintainers change positions. There is also a necessity to have maintainers opt into Biocond...

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...

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.

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 ...

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 ›

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...

🧬 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 ...
