JamendoR

Overview

JamendoR is a R wrapper for pulling track audio features and other information from Jamendo’s Web API. You can pull song and playlist information for a given Jamendo user (including yourself!) or enter an artist’s -, album’s -, or track’s name and retrieve the available information in seconds.

Installation

CRAN Version 0.1.0 (recommended)

install.packages('JamendoR')

Development version

devtools::install_github('MaxGreil/JamendoR')

Authentication

First, set up an account with Jamendo to access their Web API here. This will give you your Client ID and Client Secret. Once you have those, you can pull your access token into R with jamendoOAuth(app_name).

The easiest way to authenticate is to set your credentials to the System Environment variables JAMENDO_CLIENT_ID and JAMENDO_CLIENT_SECRET. The default arguments to jamendoOAuth(app_name) (and all other functions in this package) will refer to those. Alternatively, you can set them manually and make sure to explicitly refer to your access token in each subsequent function call.

Sys.setenv(JAMENDO_CLIENT_ID = 'xxxxxxxxxxxxxxxxxxxxx')
Sys.setenv(JAMENDO_CLIENT_SECRET = 'xxxxxxxxxxxxxxxxxxxxx')

token <- jamendoOAuth(app_name="xxxx")
filedir <- tempdir()
save(token, file=file.path(filedir, "token"))

Authorization code flow

For certain functions and applications, you’ll need to be logged in. To do this, your Jamendo application needs to have a callback url. You can set this to whatever you want, but a good default option is http://localhost:1410/ (see image below). For more information on authorization, visit the offical Jamendo Developer Guide.
