The class project for Getting and Cleaning Data 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:
- Download the zip file from this URL.
- Unzip following files:
features.txt
subject_train.txt
subject_test.txt
X_train.txt
X_test.txt
y_train.txt
y_test.txt
- Move ALL of the following files to same location
- Merge all Data sets to create a unified data set.
- Rename data attributes so user can read and understand the data
The output of the R script is a tidy data set, tidydata.txt.
You can read more about the data and the analysis in the code book.
