コロプレスの空白のフィールドを埋める方法を教えてください。私が作成したコロプレスの写真を添付しました。どうもありがとうございました!
2 つのテーブルの状態名が一致していないことに気付きましたが、生データの状態名を変更できません。
library(ggplot2)
library(maps)
**#Data looks like this:**
aggrev2015<-data.frame(

revenue=runif(50,min=100,max=9000))
state_df <- map_data("state")
colnames(state_df)<-c("long","lat","group","order","statename","subregion")
choropleth <- merge(aggrev2015,state_df, by = "statename")
ggplot(choropleth, aes(long, lat, group = statename)) +
geom_polygon(aes(fill = revenue))
