Practice project for course Getting and Cleaning Data. Free dataset comes from "Human Activity Recognition Using Smartphones Data Set".
Data set needs to be downloaded if the working repo does not contain it:
- Download the zip file from URL.
- Unzip the file.
Package reshape2 is needed to run the script
- install.packages(""reshape2")
Run the R script (run_analysis.R). The analysis script will take all the train and test data set and corresponding label to combine to be one big data table. It greps all mean and std related features and represent the label with activity description/dactor fashion.
The output of the R script is a tidy data set, tidyData.txt.
Attached code book for variable description.
