The Italian geographical aggregates nomenclature are the following:

| Function argument | Aggregates | Level | ------------|------------| -------------| | "none" | country | level 0 | | "ripartizione" | Italian divisions | level 1 | | "regione" | Italian regions | level 2 | | "provincia" | Italian municipalities | level 3 | | "comune" | Italian districts | level 4 |

where level 0 is the largest unit (country), and level 4 the smallest unit.

  # node definitions with substituted label text

  }

The diagram show the hierarchy used in the IT() to build the object to map. Smaller aggregate/levels have all the information of the bigger aggregates. For example, if we have "comune", we have also all the information until the first level, "ripartizione".

it_level0 <- loadCoordIT(unit = "none")
mappingIT(it_level0)

it_level1 <- loadCoordIT(unit = "ripartizione")
mappingIT(it_level1)

it_level2 <- loadCoordIT(unit = "regione")
mappingIT(it_level2)

it_level3 <- loadCoordIT(unit = "provincia")
mappingIT(it_level3)

it_level4 <- loadCoordIT(unit = "comune")
mappingIT(it_level4)

Note that, given the government rule, the "provincia" and district may change over the year.
