Purpose

This repository contains the Course Project for the course Getting and Cleaning Data (getdata-007) in Coursera.

Description

run_analysis.r must be run in the same directory where the source data has been unzipped. It will then

• read in the test and train datasets,
• relabel variables with descriptive names,
• add variables for the Activity and the Subject that each row of data relate to,
• merge these modified test and train datasets into a single data frame,
• create a subset with only variables on mean and standard deviation,
• calculate the mean values for each of these variables across each Subject and Activity,
• write the resulting tidy dataset as tidy.txt in the working directory
