我正在检查qtm helpfiles,但它没有说明如何更改图例百分比。
library(ggmap)
library(rgdal)
library(rgeos)
library(maptools)
library(dplyr)
library(tidyr)
library(tmap)
doe <- readOGR(dsn = ".", layer = "doesep")
qtm(doe, fill = "sep12_PERC", fill.title = "Installs")
此行qtm(doe, fill = "sep12_PERC", fill.title = "Installs")
创建此地图,但我们希望 Installs 为
0 to 24
25 to 49
50 to 74
75 to 100
如何解决这个问题?
谢谢!
