Getting and Cleaning Data

Getting and Cleaning Data Project

Raw Data

The raw data is supplied in the compressed getdata-projectfiles-UCI HAR Dataset.zip.

This compressed ZIP file must be expanded into the current working directory i.e. alongside the R scripts, such that run_analysis.R and the UCI HAR Dataset directory are next to eachother.

Tidy Data

Briefly, the tidy data in tidy_data_set.txt is a wide format file with a header row and 180 observations of 68 variables.

For me details, please refer to the code book

The Code Book

Please see CodeBook.md

The code book details the treatment of the raw data, as implemented by the R script, to produce the tidy data.

Details of the tidy data are contain in the code book also.

The R Script

Please see run_analysis.R

This script runs off the expanded raw data as described above.

The script will produce the tidy data, as describe above, in the tidy_data_set.txt file in the same directory as itself.
