This is a simple example of an application that consumes the Mendeley API. It uses the OAuth client credentials flow. For more information on the API, see the developer portal.

The application is a simple command-line script that retrieves the number of Mendeley users that have read a document with a given DOI, and produces a barplot of the readers by academic status.

Register your client at the developer portal. This will give you a client ID and secret. Save them somewhere safe - they are sensitive credentials, and once the secret is set it is never revealed again (to protect it).

1. Install R.

2. In a shell, or in Rstudio, set the MENDELEY_CLIENT_ID and MENDELEY_CLIENT_SECRET environment variables to the values you just got from the developer portal.

3. Install the dependencies declared at the top of the script.

4. Think of a DOI you would like to search for.

5. Run the script, passing the DOI in as a command line argument. You can do that like this:

    Rscript mendeley.R --doi 10.1.1.105.1540
