– Getting and Cleaning Data Course Project on Coursera
This is the readme file. This file descripes how the run_analysis.R script works.
- dplyr
The R script (run_analysis.R) does the following steps:
- Read the data set training and the data set test.
- Merges the training and the test sets to create one data set
- Extracts only the measurements on the mean and standard deviation for each measurement
- Uses descriptive activity names to name the activities in the data set
- Appropriately labels the data set with descriptive variable names
- Creates a second, independent tidy data set with the average of each variable for each activity and each subject
