Introducing shinyjs: perform common JavaScript operations in Shiny apps using plain R code

shinyjs is my second R package that managed to find its way past the CRAN review process. It lets you perform common useful JavaScript operations in Shiny applications without having to know any JavaScript. Demos You can check out a demo Shiny app that lets you play around with some of the functionality that shinyjs makes available, or have a look at a...

Introducing shinyjs: perform common JavaScript operations in Shiny apps using plain R code

shinyjs is my second R package that managed to find its way past the CRAN review process. It lets you perform common useful JavaScript operations in Shiny applications without having to know any JavaScript. Update (2015-05-31) The package has improved a lot since writing this post and some really useful functionality that I’ve been asked to implement was added. I recommend either going...

The Non-parametric Bootstrap as a Bayesian Model

The non-parametric bootstrap was my first love. I was lost in a muddy swamp of zs, ts and ps when I first saw her. Conceptually beautiful, simple to implement, easy to understand (I thought back then, at least). And when she whispered in my ear, “I make no assumptions regarding the underlying distribution”, I was in love. This love...

Animated great circles 2: smoother lines

Here is draft two of my great circle arcs R animation. This time I focused on improving the smoothness of the lines and removing some buggy line behavior, keeping it on a flat map for now. As with DRAFT 1, the YouTube video is of significantly reduced quality, to the point that you will see

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

Interactive pivot tables with R

I love interactive pivot tables. That is the number one reason why I keep using spreadsheet software. The ability to look at data quickly in lots of different ways, without a single line of code helps me to get an understanding of the data really fast...

Animated great circles 1: flat map to 3D Earth

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

Introducing the streamgraph htmlwidget R Package

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...
