The purpose of this project is to demonstrate your ability to collect, work with,and clean a data set. The goal is to prepare tidy data that can be used for later analysis.

A full description is available at the site where the data was obtained:

You should create one R script called run_analysis.R that does the following:

• Merges the training and the test sets to create one data set.
• Extracts only the measurements on the mean and standard deviation for each measurement.
• Uses descriptive activity names to name the activities in the data set
• Appropriately labels the data set with descriptive variable names.
• Creates a second, independent tidy data set with the average of each variable for each activity and each subject.
