TidyDataCourseProject

This repo contains the course project for the Coursera Getting and Cleaning Data Course. The following files are present in the directory:

• README.md -- this file
• run_analysis.R -- the R script for reading in the raw data sets (both train and test) from the Samsung data set, and extracting a tidy data set that summarizes 66 of the mean and standard-deviation features for each subject / activity group
• CodeBook.md -- the codebook file for the tidy data set that is constructed by the run_analysis.R script

Using the run_analysis.R Script

1. Place the script in your R working directory.
2. Download this zip file: https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip.
3. Unzip the archive so that the UCI HAR Dataset directory is in your R working directory.
4. Start R and type: source('run_analysis.R').
5. A tidy data set file called subj_activ_feat_summaries.txt should be generated in the working directory.
