Sets keys on data.table based in the spatial (Lon, Lat) and temporal (Year, Month, Day), present.
Description
Keys should be set on all data.table object for sorts, joins, DGVMTool-defined operators etc.
This function should be called on a data.table stored in a Field after it has been created,
including if it was created by averaging another data.table because it seems as keys are not conserved.
Usage
setKeyDGVM(dt)
Arguments
dt
The data.table for which to set the key
Value
Returns nothing because changes the original data.table by reference (this is the data.table way)
