This repository contains the course project assignment for Courseras Getting and Cleaning Data course.

Please refer to the Coursera course page for assignment details.

Content

The repository contains the following directories and files:

• UCI_HAR_Dataset the original data set on which the analysis is based on
• run_analysis.R the script that does the data cleaning and analysis (see Script for details)
• CodeBook.md that describes the data product average_by_activity_and_subject.txt
• average_by_activity_and_subject.txt the data product

Script

On high level the script:

• Reads the category and data files from the original data sets
• Combines, filters and mutates the data as the assignment instructs
• Creates a new data product as described in CodeBook.md

Further details are embedded in the comments in the script.

Script can be run with e.g. RScript run_analysis.R and it produces table formatted file called average_by_activity_and_subject.txt.
