Reproducible research and a repository of artifacts, a RFC

This  work is still in progres. I think, however, it can already resonate with some people in the community. The communication I am hopeful for should lead to a better design and maybe getting valuable tools faster. The main goal is to extend the base R’s history mechanism (see ?history) which currently gives access to … More Reproducible research and a repository of artifacts, a RFC

Izolacja w zespole i co z tego wynika

Andrzej Blikle w książce “Doktryna jakości” (dostępna do pobrania za darmo ze strony Autora) podaje przykłady organizacji, firm, instytucji, w których zarządzanie za pomocą “kija i marchewki”, zamiast spodziewanego wzrostu wydajności, przyniosło szkody.

(A Very) Experimental Threading in R

I’ve been trying to find a way to introduce threads to R. I guess there can be many reasons to do that, among which I could mention simplified input/output logic, sending tasks to the background (e.g. building a model asynchronously), running computation-intensive tasks in parallel (e.g. parallel, chunk-wise var() on a large vector). Finally, it’s … More (A Very) Experimental Threading in R

A new `subprocess` package for R

Here’s a new package that brings to R new API to handle child processes – similar to how Python handles them. Unlike the already available system() and system2() calls from the base package or the mclapply() function from the parallel package, this new API is aimed at handling long-lived child processes that can be controlled by the parent R process in a … More A new `subprocess` package for R
