Getting and Cleaning Data Project

This is a project for the Coursera online course: Getting and Cleaning Data.

There are 3 files in this project:

• README.md: this file;
• CodeBook.md: contains information about the data analysed by run_analysis.R;
• run_analysis.R: The R script that creates a new tidy dataset with the average of each variable for each activity and each subject from the raw data.

More information about the raw data can be accessed here:

http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones

To run the script you must follow these steps:

1. Download the raw data from here;
2. Extract the zip file into your R working directory;
3. Run the R script run_analysis.R. It will result in a text file named "result.txt".

Have fun!
