如何在R中的美国地图中为州上色 [英] How to color states in US map in R

问题描述

我想画一张美国地图，其中有些州为蓝色，另一些州为白色

I want to draw a US map with some states have blue color and others have white color

现在，我有了州名列表:

Now, I have the list of names of state:

c=c("ILLINOIS", "KANSAS","LOUISIANA","MAINE","MICHIGAN","MINNESOTA","MISSISSIPPI" )

但是，当我使用时:

map(database = "state",regions = c,col = "blue",fill=T)

它仅显示:

这不是我想要的，我想看到白色的其他状态，我该怎么办?

This is not I want, I want to see other states with white color, what should I do?

推荐答案

map(database = "state")
map(database = "state",regions = c,col = "blue",fill=T,add=TRUE)
