Updated 2016 September 15th: I've made this into an R package, which is available at my GitHub repository
A short post on utilising the OMIM API via some wrapper functions I wrote in R. A wrapper, as explained in the Wikipedia article, is simply a subroutine that calls another subroutine. If you plan on using the OMIM API, first register for your very own API key. After you submit the form you will get an email with the key, along with this message:
The API key will be activated within TWO hours, trying to use it before then will result in a error. It is for your own use, we ask that you do not share it with others.
So if you haven't already registered, stop reading now, and submit the form.
