Abstract:
Auxiliary cartographic components such as a scale bar, a north arrow, and labels frequently play an important role in faciliating the use of maps. Since the current R environment does not fully support these tools, we developed a scale bar for a projected map, a north arrow, and interactive text labeling with a leader arrow. The functionalities of the developed codes and noteworthy points during the execution of these functions are discussed.
