在没有ggplot2的情况下在R上绘制世界地图

Question

I'm trying to plot a world map on R but I don't have the version updated for ggplot2. Is there a way of doing it without?

Answer 1

You can get an extremely simple world map with:

library(maps)
map('world', fill = TRUE, col = 2:8, wrap=c(-180,180) )

And a somewhat better map from the mapdata package

library(mapdata)
map('worldHires', fill=TRUE, col=2:8)

And just for fun, here is a version with prettier colors, a blue ocean and cutting out Antarctica.

RegHR <- map("worldHires", namesonly=TRUE, plot=FALSE)
map('worldHires', fill=TRUE, col=terrain.colors(6),  bg="#CCEEFF",
    region=RegHR[-grep("Antarctica", RegHR)])
