A number of people have been asking about the availability of
the world map database for use with the maps library under
S-PLUS for Windows. I have created both the full and thinned
version of the databases. They are available on our ftp
site:

ftp://ftp.statsci.com/pub/support/maps/world.zip
and
ftp://ftp.statsci.com/pub/support/maps/worldthn.zip

Here is the readme file from world.zip:

This is a Windows version of the world map database from StatLib. The
database has about 2 million (latitude, longitude) pairs in it. As
such, if you try to make a full world map with map("world") you will
probably run out of memory. Smaller maps (e.g. map("world",
region=c("Spain", "Portugal")), should work fine. If you want to draw
the entire world map, get the thinned world database (worldthn.zip).

The files:
world.l
world.g
world.n
should be placed in the directory $SHOME\library\maps\data. (Typically,
$SHOME is c:\spluswin or c:\Program Files\splus4).

To test, in S-PLUS run:
win.graph() # Not needed if running S-PLUS 4.0 or a latter version
library(maps)
map("world", region=c("Canada"))

Cheers,
