The class project for Getting and Cleaning Data was to read in the ["Human Activity Recognition Using Smartphones" data set] (http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones), 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 the file.
- 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). ** Note that it requires the [reshape2 package] (http://cran.r-project.org/web/packages/reshape2/index.html), which can be downloaded from CRAN.
The output of the R script is a tidy data set, tidy.csv and tidy.txt.
You can read more about the data and the analysis in the code book.
