World Map

DESCRIPTION:

Constructs world maps. The world database comes from a cleaned-up version of the CIA World Data Bank II; the world.thin database is a smaller version.

These objects are part of the maps library. To use them in your Spotfire S+ session, type the command library(maps).

USAGE:

map("world") 
map("world.thin") 

DETAILS:

The world database contains approximately 2 million points representing the world's coastlines and national boundaries. This makes it suitable for extracting countries, continents, etc., while still retaining sufficient detail. The size of the database, however, makes it unsuitable for drawing maps of the entire world; for this purpose, use the world.thin database.

Because they require large amounts of disk space, the world and world.thin databases are not included with all Spotfire S+ installations. Both databases are installed if you do a complete (or full) installation, they are optionally installed in a custom installation, and they are not installed in a minimal installation.

The databases can be obtained in two different ways: a highly-compressed 5Mb file (in ASCII format) from the statlib file server (http://lib.stat.cmu.edu/maps).

WARNING:

Do not try to execute map("world"). It will expand the Spotfire S+ process to many megabytes and may crash your machine.
