Getting and Cleaning Data
Course Project
Hello welcome to have a look at my code! Here I create one R script called run_analysis.R that 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 activity names.
Creates a second, independent tidy data set with the average of each variable for each activity and each subject.
Steps to work on this course project
Put run_analysis.R in the parent folder of UCI HAR Dataset, then set it as your working directory using setwd() function in RStudio. Run source("Run_analysis.R"), then it will generate a new file tiny_data.txt in the working directory.
