Japan Map

Description

This database produces a map of Japan, including prefecture boundaries.

Format

The data file is merely an assignment to a character string which specifies the name of an environment variable which contains the base location of the binary files used by the map drawing functions. This environment variable (R_MAPDATA_DATA_DIR for the datasets in the mapdata package) is set at package load time.

Source

Thanks to Ritei Shibata of Keio University for the formatted data.
