This is the course project for the Getting and Cleaning Data Coursera course. The R script, run_analysis.R, does the following:
- Download the dataset if it does not already exist in the working directory
- Load all the datasets.
- Merges the two datasets
- Make the column names and activities value understandable.
- Creates a tidy dataset that consists the average of each variable for each activity and each subject.
The end result is shown in the file tidy.txt.
