Dear All, This may be a silly question, but I have tried searching through a few of the existing threads already, and haven't found any information on this. I am trying to color code entire continents/regions (Asia, North America, Africa, etc.) based on the number of relevant companies. The data would look like: World Location Companies North America 4848 Western Europe 1972 East Asia 1373 Northern Europe 313 Southern Europe 276 Middle East 167 Pacific 209 Southern Asia 156 SouthEast Asia 141 Eastern Europe 100 South America 55 Southern Africa 65 Carribean 26 Northern Africa 42 Central Asia 8 Western Africa 17 Eastern Africa 6 Central Africa 1 Central America 1 And the names/regions definitely wouldn't match in R, but if I could aggregate this data on my end to at least plot the #s in each continent that would be great. map('world', plot=FALSE)$names) gives a list of all the regions, but there are over 2000 of these regions, and I can't figure out a way to aggregate them. Any help would be greatly appreciated.
