Add Scaling directory
Here scripts and data used in scaling procedure are stored
Solved: problem of superfluous columns with rownames
Solved: getting rid only of people that do not reside in Warsaw or are too old; not also of those who have NAs as age
Changed: DataInd218.csv and "Relabelling..." script
Add Scaling/Scaling-CivicActivity.R (not yet finished)
