发布强化 shapefile

Question

我无法强化我找到的区号 shapefile here。

I 运行 install.packages("gpclib", type = "source") 按照另一个 Whosebug 问题中的说明得到以下内容：

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

我通过运行以下几行

加载文件

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

当它尝试强化时抛出错误：

Error: isTRUE(gpclibPermitStatus()) is not TRUE

我怀疑这与我在政府机器上的事实有关，我的目录不是标准的，但我真的需要解决这个问题。

我的最终目标是根据 shapefile 创建一个等值线图，其中数据由一列 phone 数字填充。形状文件中的 NPA 是区域 code/region，我需要将下面一列的前三个字符映射到该区域。

我想我已经过头了。

Answer 1

使用 rgeos 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 的功能已更新为利用 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")
