This work is a pre-grade assignment from the "Getting and Cleaning Data" Course from Coursera. In this repository you will find an R script named run_analysis.R. #Prerequisites To run this script you need to download the following zip file: https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
When the zip was downloaded please unzip it and copy the directory "UCI HAR Dataset" inside your working directory in R.
#Description This script works with test and training data included in the zip file, to generate the following:
- Merge the test and training data sets in one
- Extracts only the measures on the mean and standard deviation for each measurement
- Descriptive activity names are used in the output datasets
- Data labels are named with descriptive variable names
- A second dataset is generated from the merged one, group by activity and subject
- Both datases are saved as text files, mergedData.txt the first one and meanData.txt the grouped one
