Assignment instructions

You should 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 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.

To run the code

• Download https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip and unzip it into a directory
• set the path in R to the root of the parent directory where you unzipped the file ie. setwd("/Users/kmoir/coursera/UCI HAR Dataset")
• source("run_analysis.R")
• The result should be all_tidy_data.txt
