You can find it on Github:
The function names are the ones used in the Wrangling F1 Data With R book.
The R package needs a bit of tidying up and also needs work on the following: cacheing, so that we don’t keep hitting the ergast API unnecessarily; paged results handling (I fudge this a bit at the moment by explicitly setting a large results limit); and dual handling of ergast API versus downloaed ergast database requests (if a database connection string is passed, use that rather than make a call to the ergast API). But it’s a start… Feel free to raise issues via the repo:-)
In related news, Will Vaughan tipped me off to a Python package he’s started putting together to wrap the ergast API: ergast-python. He’s also making a start on some Wrangling F1 Data Jupyter notebooks that make use of the Python wrapper: wranglingf1data.
