Here's an interesting (at least to me) dataset for practicising regression analysis.

The data

First I installed ImageMagic (See ImageMagic documentation for installation on your OS). Then using ImageMagick's convert utility, I generated about 57 png files filled with random noise. The file dimensions go from 512px x 512px to 4096px x 4096px incrementing by 64 px in each direction.

mkdir -p ./data/RandomNoise
cd ./data/RandomNoise && \

Using arbitrary Leaflet JS plugins with Leaflet for R

The Leaflet JS mapping library has lots of plugins available. The Leaflet package for R provides direct support for some, but far from all, of these plugins, by providing R functions for invoking the plugins.

If you as an R user find yourself wanting to use a Leaflet plugin that isn't directly supported in the R package, you can use the technique shown here to load the plugin yourself and invoke it using JS code.

# Convert the JS and CSS from
# https://github.com/mapshakers/leaflet-icon-pulse/tree/master/src
# to proper URLs using rawgit.com
pluginDependency <- htmlDependency(
  "leaflet-icon-pulse",version = "1.0",
