GettingCleaningData

This repo contains a CodeBook.md file and a single R script run_analysis.R that runs analysis on the Human Activity Recognition Using Smartphones Data Set which can be downloaded from https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip

The script does the following tasks

• Imports from test dataset
• Imports from train dataset
• Add activities for each row to both datasets
• Add subjects fro each row to both datasets
• Imports variable names
• Create a subset of only mean and standard deviation variables
• Combine two datasets
• Create a list to filter by subject and activity
• Split data into a list based on subject and activity
• Calculate mean for each variable and place into new data table
• Write data to a text file
• Note that unused variables for a row are filled with NA's
