Question

我在R中创建了这个地理图表，并且在绘制图例中的NA值（黑色区域）时遇到了问题

Imgur 这是我用于映射的代码：

map<-ggplot(penetration_levels,aes(long,lat,group=region,fill=Penetration,))+geom_polygon()+coord_equal()+scale_fill_gradient2(low="Red",mid="white",high="Green",midpoint=.33,na.value="Black",label=percent)
map<-map+geom_point(data=mydata, aes(x=long, y=lat,group=1,fill=0, size=Annualized.Opportunity),color="gray6") + scale_size(name="Total Annual Opportunity-Millions",range=c(1,6))  
map<-map+borders("state", colour="black", alpha=0.8)
map<-map+theme(plot.title = element_text(size = 12))
map<-map+theme_bw()+theme(plot.background = element_blank(),panel.grid.major = element_blank(),panel.grid.minor = element_blank(),panel.border = element_blank())
map

我尝试了一些使用map + legend（）的方法并尝试了不同的方法来添加NAs作为美学，但我遇到了困难，主要问题是用户错误。

基本上我要做的是在存在填充框的情况下添加一个图例并说“没有可用的信息”＃34;

合并代码：

states<-merge(states,statelookup,by="region",all.x=T)
states<-states[order(states$order),]
penetration_levels<-merge(states,penetration_levels,by="State",all.x=T)
penetration_levels<-penetration_levels[order(penetration_levels$order),]

变量元首：
