Rcrastinate: 2018

This dance, it's like a weapon: Radiohead's and Beck's danceability, valence, popularity, and more from the LastFM and Spotify APIs

Giddy up, giddy it up

Wanna move into a fool's gold room

With my pulse on the animal jewels

Of the rules that you choose to use to get loose

With the luminous moves

Bored of these limits, let me get, let me get it like

Wow!

When it comes to surreal lyrics and videos, I'm always thinking of Beck. Above, I cited the beginning of the song "Wow" from his latest album "Colors" which has received rather mixed reviews. In this post, I want to show you what I have done with Spotify's API. We will also see how "Colors" compares to all the other albums by Beck on a range of the API's measures.

Network visualization of football transfers using the 'visNetwork' package

Click here for the interactive visualization

If you're interested in the visualisation of networks or graphs, you might've heard of the great package "visNetwork". I think it's a really great package and I love playing around with it. The scenarios of graph-based analyses are many and diverse: whenever you can describe your data in terms of "outgoing" and "receiving" entities, a graph-based analysis and/or visualisation is possible.

Send tweets from R: A very short walkthrough

There are a few reasons why you might want to send tweets from R. You might want to write a Twitter bot or - as in my case - you want to send yourself a tweet when a very long computation finishes.

So, here I will run you through all the steps you have to take using

- Twitter's API and

- the twitteR package written by Jeff Gentry

The setup to send myself tweets is the following: I have my main twitter account and an additional account I am only using to tweet from R.

Get your tracks from the Strava API and plot them on Leaflet maps

Here is some updated R code from my previous post. It doesn't throw any warnings when importing tracks with and without heart rate information. Also, it is easier to distinguish types of tracks now (e.g., when you want to plot runs and rides separately). Another thing I changed: You get very basic information on the track when you click on it (currently the name of the track and the total length).

Have fun and leave a comment if you have any questions.

Where do you run to? Map your Strava activities on static and Leaflet maps.

So, Strava's heatmap made quite a stir the last few weeks. I decided to give it a try myself. I wanted to create some kind of "personal heatmap" of my runs, using Strava's API. Also, combining the data with Leaflet maps allows us to make use of the beautiful map tiles supported by Leaflet and to zoom and move the maps around - with the runs on it, of course.

So, let's get started. First, you will need an access token for Strava's API.
