#Getting and Cleaning Data ##Peer Assessment ###Introduction This script runs analysis on the Samsung sensor data. 30 subjects perform 6 activities, the scripts returns the mean and standard deviation and averages over all measurements for each subject for each activity.

###How to use The "UCI HAR Dataset" folder should be placed in the same directory as the script. There is only a single function in this script. run_analysis() returns the tidied data frame and also writes the data frame to tidy.txt in the same directory

###How it works

• Read in data, activity label number, label names, subject IDs for test and train
• Merge test and train file pairs where applicable
• Give label numbers their associated activity names
• column bind subject, activies and measurements
• Add column names from full features list
• Keep only columns with mean() and std() in the name
• Order the data with subject then activity
• Evaluate mean for subject and activity
