我试图在地图上绘制垂直条形图.我在线浏览了一些例子,但不知怎的.
我的数据目前采用以下格式:
University| Count | Category | lat | long
这是我正在尝试执行的代码:
library(ggplot2)
library(ggmap)
library(ggsubplot)
df1 <- data.frame(
University = c(rep("University1", 4), rep("University2", 4), rep("University3", 4),
rep("University4", 4)),
Count = sample(1:10, 16, replace = T),
Category = rep(c("A", "B", "C", "D")),
lat = c(rep(10.902469, 4), rep(17.921959, 4), rep(18.606910, 4), rep(13.202366, 4)),
long = c(rep(76.90020, 4), rep(83.42510, 4), rep(73.87501, 4), rep(77.62340, 4))
)
india <- get_map("India", zoom = 5)
p <- ggmap(india)
p + geom_subplot(data = df1, mapping=aes(x = long, y = …
