You can additionally specify the year (year) and scale (1:scaleMillion) of the downloaded shapefiles as follows:nf=NutsFinder(year=2013,scale=60)Note that the default year is the latest available, and the scale is the median available. At time of writing the available years were{2003, 2006, 2010, 2013, 2016}and available scales were{1, 3, 10, 20, 60}.Points near rivers and coastlinesUnless you usescale=1, expect to lose some coverage of points very near to water features (coastal and river regions). If you would like to optimise for speed, you might consider a recursive strategy of using a coarserNutsFinderfollowed by a more granular one to pick up missed points.Speed-upsThefind(...)method is significantly faster for coarser geographical scales. For most purposes, a scale of around 10 should be sufficient.
