The class project for Coursera (https://www.coursera.org/course/getdata) was to read in the "Human Activity Recognition Using Smartphones" data set, perform an analysis on the data set, and output a tidy data set.

Here are the steps that must be performed before running the R script:

Note that it requires the reshape2 package

1. Download the zip file from this URL.
2. Unzip the file.
3. Move ALL of the following files to the SAME DIRECTORY as the R script:
   • features.txt
   • subject_train.txt
   • subject_test.txt
   • X_train.txt
   • X_test.txt
   • y_train.txt
   • y_test.txt

Once those steps are complete, you can run the R script (run_analysis.R).

The output of the R script is a tidy data set, tidy.csv.
