Working of script:

  • Script should be kept inside the "UCI HAR Dataset" directory
  • Once run, it creates a folder named "merged", where you will see a merged file for every file from "test" and "train" directories, in the same directory structure.
  • X_merged and y_merged files are than modified by adding column names and row annotations to create a new dataset named "annotated.dataset"
  • "annotated.dataset" is then aggregated to create a tidy data set saved in file "tidy.dataset"

Codebook:

####New files:

  • run_Analysis.R : contains the script
  • tidyDataset.txt : Tidy dataset after following all steps
  • merged.rar : Directory of merged datasets

####Variables in tidyDataset.txt:

  • ActivityName: Descriptive name of activity added to new dataset
  • SubjectID: Subject label added to new dataset
  • All additional columns are features from the original dataset
