R Tagosphere!

Sun, 31 Jan 2016 17:41:10 +0000

This post explores the inter-relationships of StackOverflow Tags for R-related questions. So I grabbed all the questions tagged with “r”, took the other topics: in each question and made some network charts that show how often each tag is seen with the other topics:. The point is to see the empirical relationships that develop as people organically describe their problems with R. Full analysis on GitHub, as always.

Locations for 75000 dams

Tue, 20 Oct 2015 20:30:39 +0000

The last task I performed for [[AQUASTAT]] was to try to find the best way to estimate the anthropogenic evaporation from dams. The paper can be found here, but here I provide one of the fun outputs, a map of 75000 dams!

Transboundary surface water flow

A [[Visualization]] generated for [[AQUASTAT]] of [[FAO]].

Two types of charts were prepared: Sankey and Network. The Sankey plots allow for an ‘automatic sorting’ of countries based on who is the water tower and who is the water source. This [[Visualization]] is useful to demonstrate where a country falls on this continuum.

Chord progressions of 5000 songs!

Sun, 01 Mar 2015 00:00:00 +0000

Update: Full analysis and everything you need at my github https://github.com/datastrategist/Musical-chord-progressions

The Hooktheory.com database contains analyses of over 5000 songs*. These analyses are uploaded by users and allow for all these songs to be analyzed in bulk, as well as individually. One of these ‘all song’ analyses enables users to gather chord progressions on ALL songs (see the analysis file to see how i did it, using the hooktheory API and R). This allowed us to create a Sankey [[Visualization]] of all chord progressions in the Hooktheory database.
