I’ve been using the iOS Sleep Cycle app to track my sleeping since late 2014 and have accumulated quite a bit of information about my sleeping habits. I wanted to see if I could do some exploratory data analysis and try out some different packages to clean up and visualize my data. The data from the app comes in a csv file and contains information like date, sleep quality, sleep duration, and more recently it can integrate with the pedometer so you can get the number of steps in a given day.
