The shell script was used to clean the data and upload it to BigQuery. You can access the data yourself there:

https://bigquery.cloud.google.com/table/nypd-data:nypd.stop_and_frisk

Or if you simply want a giant zip of CSV files, go here (note: You'll have to do the work of reconciling the columns in order to get all the files into one database):

The R script in this gist produces the image below:

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Basic Workflow

Description

Different uses of git will have a different optimal workflow. This document describes a git workflow with the following characteristics:

• It is a centralized workflow, meaning multiple developers all push to a shared repository. (As opposed to a fork-and-pull-request Github-style workflow.)
• It is safe to use when collaborating on a feature branch with others, but requires no workflow changes when working alone. (So there's only one set of steps to remember.)
• Some git users rely heavily on rebases, using them for any and all conflicts. This is an unhealthy coping mechanism born of past git merge trauma. This workflow relies heavily on merges, using rebase only when it is safe to do so (with commits that have yet to be pushed).
• push --force is never needed (and may be disallowed by the remote repository.)
