================================================================== Human Activity Recognition Using Smartphones Dataset Summary and Aggregation Version 1.0 ================================================================== KaraLea Follmer https://github.com/kfollmer24/Course_Project ================================================================== This program aggregates and summarizes the "Human Activity Recognition Using Smartphones Dataset: Version 1.0" Created by Smartlab - Non Linear Complex Systems Laboratory. The program completes the following steps: ====================================== - Read the necessary lookup tables - Read the training and test data and place them together in one data set - Add the variable names - Use dplyr package to take the mean and sd of every variable - Match the activities to activities names based on the associated reference number - Create a data set that takes the mean of every variable by subject and activity (30 subjects * 6 activities = 180 mean calculations) - Output that final dataset Packages Used: ====================================== dplyr It outputs the following: ====================================== A data set that takes the mean of every variable by subject and activity (30 subjects * 6 activities = 180 mean calculations)
