Code & data accompanying "whole-game" youtube video

building-permits

This repository provies the code and data accompanying my "whole game" intro to data science video. The goal of this video is to quickly outline all the parts of a data science project so you get an overview of how everything hangs together, and see a little bit of my workflow.

• permits-actual.md: this is the actual code I typed during the video

• permits-practice.md: practice code that I wrote beforehand. The code is a little nicer and it has more comments.

TODO

• Figure out how to show keyboard shortcuts on screen

Capturing shortkeys

I'm planning on doing a similar test run for YouTube tutorials, and assuming you're predominantly doing these on macOS, I'd like to recommend keycastr. It's simple, it does the job, and it should work nicely for your use case. You can install it via brew cask install keycastr and need to give it accessibility access, and then it just lives in your menu bar and is ready to go.

Hope this helps,
hope to see more videos soon :)

Year-month data type

I enjoyed the video; we all should do more of this. It is useful to look over other people's shoulders and see how they work.

One thing that struck me in need of clear improvement: your timepoints should really not be a numeric of year + (month-1)/12. The chron package has been on CRAN since the 1990s, it has yearmon. And of course the ts object is designed for series with a regular increment like a month or quarter. Neither one of these may qualify for "tidy" but I think it would make for nice gesture towards "all of R" to also use containers from base R.

[ And converting back and forth is hard. I did some work with code by the NY Times which (explicitly) deseasonalized for it required ts objects. They had started from a pretty "tidy" codebase but had to add a ton of ad-hoc converters to go from data.frame (or tibble) to ts and back. The current (frozen) snapshot of the CRAN package I made of this in this NYTimes repo which they let me push to. ]
