The data set used as base information for this script is:
https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
Data from train and test data sets was joined and tagged in order to generate a new data set will all information.
The values are an average of each mesure by each original variable, where x, y, and z defines a vector and "mean" is the mean value and "std" is the standard deviation:
