#Class Project for "Getting and Cleaning Data"

The project required reading the "Human Activity Recognition Using Smartphones" data set from https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip

This data set should be extracted into the R working directory.

An R script called run_analysis.R can be executed to:

• Merge training and test data sets to create one data set
• Extract only mean and standard deviation measurements
• Use descriptive activity names to name the data set activities
• Appropriately label the data set with descriptive variable names.

From this data set (data_set.txt), create a tidy data set (tidy_data.txt) with the average of each variable for each activity and each subject.
