R 问题强化形状文件

我无法加强找到的区号形状文件

我按照另一个Stackoverflow问题中的说明运行了

install.packages（“gpclib”，type=“source”）

，得到了以下结果：

The downloaded source packages are in
    ‘C:\Users\wol1\AppData\Local\Temp\1\RtmpInWyln\downloaded_packages’

我通过运行以下行来加载文件

library("maptools")
library("ggplot2")
area <- readShapePoly("AreaCode.shp")
fort.area <- fortify(area, region = "NPA")`

sessionInfo（）

我想我已经超过我的头了

使用软件包而不是

gpclib

由于许可限制，

gpclib

在

maptools

中被弃用，并被

rgeos

取代。默认情况下，

maptools

中依赖于

gpclib

的功能已更新为使用

rgeos

R> install.packages("rgeos")
R> library("maptools")
Loading required package: sp
Checking rgeos availability: TRUE
R> library("ggplot2")
R> area = readShapePoly("AreaCode.shp")    
R> fort.area <- fortify(area, region = "NPA")

R>install.packages（“rgeos”）
R> 库（“地图工具”）
正在加载所需的包：sp
检查rgeos可用性：TRUE
R> 图书馆（“ggplot2”）
R> 面积=readShapePoly（“AreaCode.shp”）
R> fort.area请编辑您的问题并添加
sessionInfo（）
的输出。我已经添加了会话信息。嗯，请删除
gpclib
包，然后再试一次，代码在我的计算机上使用
rgeos
。多么简单，令人沮丧；它现在工作得很好。我已将您标记为正确答案，谢谢您的帮助！
