Getting and Cleaning Data - Project

Source dataset https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip.

The R script 'run_analysis.R' performs the following tasks:

• 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 activity names.
• Creates a second, independent tidy data set with the average of each variable for each activity and each subject.

Notes

• Only vaiables containing mean() & std() are used.
• Requires the plyr & reshape2 packages.
• It does not assume the dataset is unzipped in the current directory and will try to download it if not present
