我正在使用rworldmap,并且我想将汇总的国家数据绘制为区域。我看到有一些名为mapbyregionand的函数country2Region,但如果我理解正确,这些区域是预定义的,例如 Stern 区域。我想使用我自己选择的区域?这可能吗?可以用另一个包完成吗?

我有一个带有 iso3 代码的数据框,我可以在其中说明一个国家所属的地区(我可以对其进行编辑以进行自己的分组。例如,欧盟国家、高收入国家等)。

其中之一应该会有所帮助。

library(leaflet)
library(htmltools)

# example from ?leaflet
m = leaflet() %>% addTiles()

# there are two approaches to the custom css problem
#  1.  the easy but less robust way
browsable(
  tagList(list(
    tags$head(
      # you'll need to be very specific
      tags$style("p{font-size:200%;}")
      # could also use url
      #tags$link(href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css",rel="stylesheet")
    ),
    m
  ))
)





#  2.  you can add dependencies to your leaflet map
#  this mechanism will smartly handle duplicates
#  but carries a little more overhead
str(m$dependencies)  # should be null to start
# 
m$dependencies <- list(
  htmlDependency(
    name = "font-awesome"
    ,version = "4.3.0"
    # if local file use file instead of href below
    #  with an absolute path
    ,src = c(href="http://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css")
    ,stylesheet = "font-awesome.min.css"
  )
)
