使用csv文件在R中的地图上绘制坐标的新手

Question

我是 r 的新手，几个小时以来一直在尝试在亚利桑那州地图上绘制蝴蝶家族的点。我可能做错了，或者我不确定有什么遗漏，将不胜感激任何帮助！

我现在有以下代码并尝试了很多其他代码：

rio = read.csv("Rioninidae_Cleaned.csv",stringsAsFactors = FALSE)
arizona <- get_googlemap(center=c(lon=-110.713,lat=31.815), zoom = 3)
lon <-data.frame(rio$latitude)
lat <-data.frame(rio$longitude)
df <- as.data.frame(cbind(lon,lat))
df
arizona <- get_googlemap(center = c(lon = -110.713,lat = 31.815), zoom = 3)
ggmap(arizona) +
  geom_point(data = df, aes(x = lon, y = lat), size = 5, shape = 21) +
  guides(fill = FALSE, alpha = FALSE, size = FALSE)

我的 csv 文件位于：https://www.dropbox.com/s/yxj1uvmt9bw8gvn/Rioninidae_Cleaned.csv?dl=0

       genus province         county latitude longitude
1   Apodemia  Arizona         Apache 33.90011 -109.5844
2   Apodemia  Arizona Cochise County 31.46260 -110.2895
3   Apodemia  Arizona Cochise County 31.46260 -110.2895
4   Apodemia  Arizona    Santa Cruz  31.50503 -110.6547
5     Emesis  Arizona     Santa Cruz 31.74001 -110.9411
6     Emesis  Arizona     Santa Cruz 31.74001 -110.9411
7     Emesis  Arizona     Santa Cruz 31.38333 -111.0833
8   Apodemia  Arizona     Santa Cruz 31.38333 -111.0833
9 Calephelis  Arizona           Pima 31.76667 -111.5500

谢谢！

我猜你可能正在寻找这样的东西。

library(ggmap)
library(ggplot2)

# Get a map
arizona <- get_map(location = c(lon = -110.713, lat = 31.815), zoom = 6)

ggmap(arizona) +
geom_point(data = mydf, aes(x = longitude, y = latitude, fill = genus), size = 3, shape = 21)

数据

mydf <- structure(list(genus = structure(c(1L, 1L, 1L, 1L, 3L, 3L, 3L, 
1L, 2L), .Label = c("Apodemia", "Calephelis", "Emesis"), class = "factor"), 
province = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L
), .Label = "Arizona", class = "factor"), county = structure(c(1L, 
2L, 2L, 5L, 4L, 4L, 4L, 4L, 3L), .Label = c("Apache", "Cochise County", 
"Pima", "Santa Cruz", "Santa Cruz "), class = "factor"), 
latitude = c(33.9001056, 31.4625978, 31.4625978, 31.5050272, 
31.7400056, 31.7400056, 31.38333333, 31.38333333, 31.76666667
), longitude = c(-109.58444, -110.2895241, -110.2895241, 
-110.65472, -110.94111, -110.94111, -111.0833333, -111.0833333, 
-111.55)), .Names = c("genus", "province", "county", "latitude", 
"longitude"), class = "data.frame", row.names = c(NA, -9L))
