Week 4 project - Getting and Cleaning Data in R

Author -- Benedict Neo

This is the final project from the Coursera course Getting and Cleaning Data by John Hopkins. The purpose of this project is to demonstrate my ability to collect, work with, and clean a data set.

Repository contents

This repository includes 4 files, the R script named run_analysis.R, this read_me file you're reading now, the codebook file which explains more about the data set and the methodology, and the final tidy data set.

Project theme

Getting and Cleaning Wearables Computing Data

One of the most exciting areas in all of data science right now is wearable computing - see for example this article . Companies like Fitbit, Nike, and Jawbone Up are racing to develop the most advanced algorithms to attract new users. The data linked to from the course website represent data collected from the accelerometers from the Samsung Galaxy S smartphone.
