This repository contents the script file (run_analysis.R) to tidy and summarise wearable data set that can be found in http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones.

Also it is included the code book (codebook.md) of the final tidy and summarised data set.

Other files are included for explanation of the original variables that are found in the original data set (feature_info.txt and features.txt).

To use this 'run_analysis.R' you need to download the original data set from http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones

Unzip the folder 'UCI HAR Dataset.zip' and put in your working directory the folder 'UCI HAR Dataset'. Then run the script.

The final data set will be saved in the workking directory with the name "average_tidy_dataset.txt"
