Getting and Cleaning Data Assessment
There is only one R file:run_analysis.R, which is creating tidy data.
run_analysis.R is doing following steps:
- reads and prepares header names
- reads both test and train data and binds them to appropriate dataframes
- 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 activity names.
- creates independent tidy data set with the average of each variable for each activity and each subject.
- write output
