我无法强化在此处找到的区号 shapefile 。
我install.packages("gpclib", type = "source")按照另一个 Stackoverflow 问题中的说明运行并得到以下信息：

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")`
当它试图强化它时会抛出错误：
错误：isTRUE(gpclibPermitStatus()) 不是 TRUE
我怀疑这与我在政府机器上并且我的目录不是标准的事实有关，但我真的需要解决这个问题。
我的最终目标是从 shapefile 创建一个等值线图，其中的数据由一列电话号码填充。NPA形状文件中是区号/区域，我需要将下面列的前三个字符映射到该区域。
