Use the script file run_analysis.R to obtain a tidy dataset from the Human Activity Recognition version1 Dataset.

The creation of a directory "GettingData" in your HOME folder is optional (and commented out) as is the downloading of the data. Anyway, the data should be in a folder located in your working directory and named UCI HAR Dataset, as it is normally after unzip.

The only required package is dplyr, to be installed before running the script.

The file CodeBook.md explain the transformations made to the data to obtain eventually the tidy dataset, named tidy_data and exported as tidy_data.txt.

R version: i386 (32 bits) 3.2.1
