At the moment, each of the 4 script requires a manual data entry of the "NSEjaar" (year of the NSE questionnairre data). However, usually all four scripts will be run for the same year, so a more centralized definition of NSEjaar could be beneficial. @ALeemans recommends to use the use of a global variable, for instance defined in another .RData (?) file, that is only set once and then imported in each script.
