This repository contains my course project for the Coursera course "Getting and Cleaning data."
The UCI HAR Dataset is available at this link: https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
The UCI HAR Dataset must be downloaded, and extracted into a directory called "data" in your working directory.
The R script called run_analysis.R does the following:
- Merges the training and the test sets to create one data set.
- Extracts only the measurements on the mean and standard deviation for each measurement.
- Uses descriptive activity names to name the activities in the data set
- Appropriately labels the data set with descriptive variable names.
- From the data set in step 4, creates a second, independent tidy data set with the average of each variable for each activity and each subject.
Explains the transformations performed and the resulting data and variables.
