GettingCleaningData
Contents
There are two files: CodeBook.md and run_analysis.R.
run_analysis.R transforms the Human Activity Recognition data to two tidy forms. 1)where each row corresponds to an observed activity and each column to observed mean and standard deviation over a variety of measurements, as well as activity and test subject, saved as activityaveragebysubjectactivitydata.txt 2) where each row corresponds to a pair of test subject and activity, and columns are means of the measurements in 1) over all observed cases of a particular activity and subject saved as activitydataclean.txt
The codebook describes the variables included.
