Get_Clean_Data_Project

Course project for Getting and Cleaning data course offered on coursera.

To run the run_analysis.R script:

• Download the data folder from the link on the course website, https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip.

• Change the setwd() line of code at the beginning of the R script to match your working directory.

• When you source the code, it will automatically place the tidy dataset in your working directory.

What run_analysis.R actually does:

• Pulls in the test and training datasets (X_test.txt and X_train.txt)

• Adds descriptive variable names to both datasets (features.txt)

• Pulls in and adds columns for subject and test name (subject_test.txt, y_test.txt, subject_train.txt, y_train.txt)

• Converts the test numbers into descriptive labels (activity_labels.txt)

• Consolidates the test and training datasets into 1 dataset

• Limits to columns that only contain "mean()" or "std()"

• Finds the average of the remaining variables for each subject/activity combination
