[R] Map of British Colonial America 1775

[Spencer Graves]

      Does anyone have suggestions about how to produce a map of British 
Colonial America 1775?  At that time, Great Britain had 26 colonies in 
the Americas, including Bermuda, several Caribbean islands, "Quebec" 
(extending then almost to New Orleans), Nova Scotia, Newfoundland, 
Belize, and the 13 that declared independence in 1776. 

      I've reviewed the "map" documentation I've found so far with 
S-Plus 6.2 and R including "www.r-project.org" -> search -> "R site 
search" -> "world map" and Becker & Wilkes (1993) "Maps in S" cited in 
the "map" documentation.  I've noticed that, for example, 
'library(maps);  map("world", "UK:Bermuda")' produces an 83-point 
polygon sketch in S-Plus 6.2 but only a degenerate 3-point polygon (with 
the third point = the first) in R 1.8.1. 

      Thanks, Spencer Graves
