Git repository for Getting and Cleaning Data Coursera project. The goal of this project is to produce a tidy data set for later analysis.
The data are as received from UCI and placed in the directory ../data/
The script reads the following from ../data/UCI_HAR_Dataset:
- activity_labels.txt -- contains the conversion from numerical to descriptive activities
- features.txt -- contains the column labels for the data sets
- train/X_train.txt test/X_test.txt -- contains the readouts for the different variables
- train/y_train.txt test/y_test.txt -- contains the activity labels for each of the observations in the X files
Outputs are two CSV files in the UCI_HAR_Dataset directory: data_set.csv -- contains all data pertaining to mean and stdev agg_data_set.csv -- contains means for each variable by subject and activity
