Code Book

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.

  1. 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"
  2. 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.
  3. 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"
  4. 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
  5. 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
