A few months ago I published A Short API Reading List with some articles I came across while writing v1 of SigOpt’s API. Here, I share some articles that I bookmarked while working on our R API Client.
There are many different definitions of a data scientist, but there are two very common languages: Python and R. At SigOpt I work primarily in Python, so I had no trouble writing code for our Python API Client. However, it soon became apparent that an R API Client would be very useful for many of our customers! The only problem was that I did not know R. Luckily, R has an avid open source community that has written lots of tools and tutorials. Here are some articles and step-by-step guides that I founds extremely helpful while developing SigOpt’s R API Client.
Best practices for writing an API package by Hadley Wickham. This vignette is your step-by-step guide to writing the R API Client. I came in with no prior experience in R and it took me an afternoon to get my first .R file with my three initial endpoints up and running.
I don’t think you can write something in R without coming across Hadley Wickham’s name. He is an avid contributor to the R community and his work is what made writing this package so easy.
Rstudio-server environment variables not loading? on StackOverflow. R environment variables are set in a special file (.Renviron), or via a command from within R. Hopefully this StackOverflow discussion will save you some frustration.
Writing an R package from scratch by Hilary Parker. Writing an R package doesn’t have to be daunting! Packages like roxygen2 and devtools auto-generate a lot of the boilerplate, and allow you to do cool things like install packages directly from Github. Hilary Parker has written a step-by-step tutorial that guides you through these tools. Put the single .R file from the “developing” section into the R folder in this tutorial, write your DESCRIPTION, and let devtools handle the rest!
Building and R Project with Travis CI. We use Travis for testing on GitHub. If you’ve never used it before, it’s a great way to automatically run test suites, especially after things like pull requests or pushes. I used Encrypted Variables to setup a development API token in the public build so that we could test real API calls.
