Tidying the UCI HAR Dataset

This is an R script to process the UCI HAR Dataset into a tidy data format.

How to use

The code to download and process the dataset is in the run_analyis.R file.

To do the processing source the file into your R environment.

source('run_analysis.R')

This will export two derived data.frames into your global environment:

• UCI.HAR.tidy
• UCI.HAR.averaged

Data Source

The UCI HAR Dataset is described in detail here and can be fetched from a mirror here.

Code Book

A CodeBook describes the UCI.HAR.tidy and UCI.HAR.averaged data frames, their variables, and the data transformations used to derive them.
