Generating the data set

The R script run_analysis.R is provided to generate the summary data set in CSV form.

1. Download the UCI HAR Dataset: https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
2. Unzip the file. A directory named UCI HAR Dataset should result.
3. Execute run_analysis.R with UCI HAR Dataset as the working directory. The CSV file is written to stdout.
   • Optionally the R script could be edited to write the CSV file to some location in the filesystem.
   • On unix-like systems the shell script ./run_analysis.sh will run the R script using R CMD BATCH and redirect the output to run_analysis.csv. It expects to be called from the project directory and requires the subdirectory UCI HAR Dataset to be there.
