R packages with unlimited licenses

I had an interesting email today saying that developers at the writer’s company wanted to use one of my packages, but weren’t allowed because it was under an unlimited license. I release quite a few of my packages under an unlimited licence, at least for toy projects and immature packages. In those cases, letting users

By

A pure maintenance release 0.1.3 of the RcppDE package arrived on CRAN yesterday. RcppDE is a "port" of DEoptim, a popular package for derivative-free optimisation using differential optimization, to C++. By using RcppArmadillo, the code becomes a lot shorter and more legible.

Modern Honey Network Machinations with R, Python, phantomjs, HTML & JavaScript

This was (initially) going to be a blog post announcing the new mhn R package (more on what that is in a bit) but somewhere along the way we ended up taking a left turn at Albuquerque (as we often do here at ddsec hq) and had an adventure in a twisty maze of Modern Honey Network...

A better interactive neuroimage plotter in R

In a previous post, I described how you can interactively explore a 3D nifti object in R. I used the manipulate package, but the overall results were sluggish and not really usable. I was introduced to a a good neuroimaging viewer called Mango, by a friend or two and use it somewhat inconsistently. One major

Track Hurricane Danny (Interactively) with R + leaflet

Danny became the first hurricane of the 2015 Season, so it’s a good time to revisit how one might be able to track them with R. We’ll pull track data from Unisys and just look at Danny, but it should be easy to extrapolate from the code. For this visualization, we’ll use leaflet since it’s
