Peer-graded Assignment: Getting and Cleaning Data Course Project Submission by : Kevin Benny(kevinbenny@karunya.edu.in) It has the instructions on how to run analysis on Human Activity recognition dataset.
Dataset used in the project Human Activity Recognition Using Smartphones
Files CodeBook.md a code book that describes all the variables , data and transformations perfored with the dataset
'run_analysis.R' performs the data preparation and then followed by the 5 steps required as described in the course project’s definition:
- Merges the training and the test sets to create one dataset.
- Extracts only the measurements on the mean and standard deviation for each measurement.
- Uses descriptive activity names to name the activities in the dataset
- Giving labels to the dataset with descriptive variable names.
- From the dataset in step 4, creates a second, independent tidy data set with the average of each variable for each activity and each subject.
- IndependentData.txt is the exported final data after going through all the sequences described above.
