Animated paths in R: toy example

Recently I have shared examples of animations made using R which feature traversal of pathways, specifically grid cell borders and great circle arcs. Here I provide the basic code required to generate a path sequence from a path. The fundamental ideas are as follows: Pathways are represented by lines. Lines are represented by a series

Animated great circles 1: flat map to 3D Earth

More fun with great circle arcs. Who doesn’t love a good great circles graphic? This time, however, it is an animation. Using R, not only have I animated path traversal along great circle arcs, but I’ve also projected them onto a three dimensional global surface. It was not without its challenges. And yes, the title

We were looking for a different type of visualization for a project at work this past week and my thoughts immediately gravitated towards streamgraphs. The TLDR on streamgraphs is they they are generalized versions of stacked area graphs with free baselines across the x axis. They are somewhat controversial but have a “draw you in”

Mapping IPv4 Address (with Hilbert curves) in R

While there’s an unholy affinity in the infosec commuinty with slapping IPv4 addresses onto a world map, that isn’t the only way to spatially visualize IP addresses. A better approach (when tabluation with bar charts, tables or other standard visualization techniques won’t do) is to map IPv4 addresses into Hilbert space-filling curve. You can get a good feel...

The National Centre for Biotechnology Information (NCBI) is part of the National Institutes of Health’s National Library of Medicine, and most well-known for hosting Pubmed, the go-to search engine for biomedical literature - every (Medline-indexed) publication goes up there. On a separate but related note, one thing I’m constantly looking to do is get DOIs for papers on...

A Letter of Recommendation for Nan Xiao

I hope my letter could boost this guy up like: I'm not sure if I'm a good observer, but time and time again I feel some people are undervalued, or they were not given better opportunities to show their value. Not surprisingly, I know quite a few such people in the Chinese R/stats community, mainly because of the...
