    <p>`updateFarmData()` creates sample farms by aggregating data based on the weighted mean and the selected mapping for use in FarmDyn.
For non-numerical globals, it summarises based on the mode using the `Modes()` function. When `writegdx` is `TRUE`, it writes the GDX in the format 'farmData_(mapping).gdx'.</p>
