This post introduces a new R package I am working on called tabr for creating guitar tablature (“tabs”) from R code. The tabr package provides programmatic music notation and a wrapper around LilyPond for creating quality guitar tablature. [Click here for original post] (in process of switching where I post ...

Make memorable plots with memery. memery is an R package that generates internet memes including superimposed inset graphs and other atypical features, combining the visual impact of an attention-grabbing meme with graphic results of data analysis. Version 0.4.2 of memery is now on CRAN. The latest development version and a package ...

The shinydashboard package provides functions like valueBox that conveniently display basic information like summary statistics. In addition to presenting a value and subtitle on a colored background, an icon may be included as well. However, the icon must come from either the Font Awesome or Glyphicon icon libraries and cannot ...

mapmate has now been updating from version 0.0.2 to 0.1.0 on Github. The biggest addition is a number of plotting options for making different kinds of maps. The new tutorial content below provides a number of code examples for making a variety of maps and also highlights current limitations associated with certain ...

Introduction to mapmate mapmate (map animate) is an R package for map animation. It is used to generate and save a sequence of plots to disk as a still image sequence intended for later use in data animation production. The mapmate package is used for map- and globe-based data animation ...

Making still frames for great circle animations in R Matthew Leonawicz Here I share R code I used to produce animated great circle arcs on top of a rotating 3D Earth. The code is not entirely reproducible but you should be able to use what is shared here to create ...

Using leaflet in R is fairly simple and there are plenty of online resources and examples available already. See the RStudio tutorial to get started if you haven’t already. This post presents a series of examples which build upon each other. The code displays both point data and raster ...

In this post I share an R Shiny app which uses the leaftlet package for interactive maps. This app differs from prior apps I’ve made featuring leaflet maps. First, it displays rasterized map data rather than just point layers. Also, longitude and latitude sliders in the browser allow for ...

Here is the final draft of my great circle arcs R animation. I made this back in January shortly after my first two drafts, but am only now getting around to sharing it, which is a typical representation of how seldom I can make time for blogging. But given the ...

Here’s an interesting R plot comparing a specific air pollution metric between Fairbanks, Alaska and Beijing, China. Right off the bat, Beijing obviously has far worse air quality, and more significantly, it is a chronic, daily problem. But it is used for comparison because we already know this is ...

Lightning activity is projected to increase with climate change. Lightning activity is interesting to model with stochastic gradient boosting (GBM: generalized boosted regression models/gradient boosting machine) in R. One use I have for this at SNAP is in the context of landscape fire modeling with SNAP’s ALFRESCO model. ...

I have approached a final draft of my Community Charts version 4 Lite, now with leaflet map integration. This R Shiny web application shows projected climate trends for various Alaska and western Canada communities. Note that if no other users are already connected to the app, it will take a moment (...

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 ...

[Alpha] and [beta] versions of a simple R Shiny web application showing projected climate trends for various Alaska and western Canada communities is available. [The alpha and beta versions are currently nonfunctional. But you can skip to the final version here. Some of the text below only pertains to the ...
