I’m beginning to use and explore NetLogo. For one of my study codes I would like to divide my world in 4 different, but equal, quadrants – just like the Cartesian coordinate system – using patches coordinates.

The furthest I got, reading other questions here, was to divide the world in two parts, as that:

ask patches [
   ifelse (pycor > 0)
    [set quadrant 1]
    [set quadrant 2]

And something in that way, I think, should be what I need.
