The "run_analysis.R" will read data which can be downloaded from https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
run_analysis.R" has the following functionality.
- Merges the training and the test sets to create one data set
- "/train/X_train.txt" with "/test/X_test.txt"
- "/train/subject_train.txt" with "/test/subject_test.txt"
- "/train/y_train.txt" with "/test/y_test.txt"
- Extracts only the measurements on the mean and standard deviation for each measurement
- It gets list of measurements from "/features.txt"
- Extracts only the measurements on the mean and standard deviation for each measurement
- Applied on result data set from "/train/X_train.txt" with "/test/X_test.txt" and used as labels.
- Uses descriptive activity names to name the activities in the data set
- It gets activities from "/activity_labels.txt"
- Based on activity code in result data set from "/train/y_train.txt" with "/test/y_test.txt" it joins data to the data set from "/activity_labels.txt" and replaces activity codes with activity labels.
- Name the variable "activity"
- Appropriately labels the data set with descriptive variable names
- Name the variable "subject" in result data set from "/train/subject_train.txt" with "/test/subject_test.txt"
- Merge all three results data sets from the step one above.
- Create "tidy.data.set" data frame
- Creates a second, independent tidy data set with the average of each variable for each activity and each subject
- Create "tidy.data.set.mean" which is derived from "tidy.data.set"; get mean of each column by activity and subject
- Export "tidy.data.set.mean" data into "tidy.data.set.mean.txt" in current working directory
