# Getting and Cleaning Data project
This readme gives an overview of the project structure and the scripts.
## Scripts
### `download.R`
* downloads the data for the project, saving it as `dataset.zip` (skipped if `dataset.zip` already exists),
* extracts it into the working directory.
The zip has a single root directory `UCI HAR Dataset`, so it will not pollute the working directory with individual files.
This script is for convenience only, downloading and extracting may be performed manually, too.
### `run_analysis.R`
The goal of this script is to produce the tidy dataset. For that end it
* reads the raw data from various files in the `UCI HAR Dataset` directory (relative to the working directory),
* performs the merging and cleaning steps as per the project specification,
* saves the tidy dataset in CSV format as `tidy.txt` in the working directory.
This script assumes the dataset zip file is already extracted and data files are present in the `UCI HAR Dataset` directory.
It requires the [reshape2](http://cran.r-project.org/web/packages/reshape2/index.html) R package.
## Code book
The code book for the project is in `CodeBook.md`, which describes the variables, the data, and transformations performed by `run_analysis.R`.
