Question

我在R中遇到导致程序崩溃的问题。我终于能够将问题缩小到以下几个方面。

我发现以下工作：

library(rgeos)
x = readWKT("POLYGON ((0 0, 0 10, 10 10, 10 0, 0 0))")
gIsValid(x)
[1] TRUE

但是，以下结果导致崩溃：

library(rgdal)
x = rgeos::readWKT("POLYGON ((0 0, 0 10, 10 10, 10 0, 0 0))")
rgeos::gIsValid(x)

在我正在处理的R套餐中，rgdal在＆＃34; Depends＆＃34;和rgeos＆＃34; Imports＆＃34;下指定。在描述文件中。所以我的代码表现得更像第二个（崩溃）场景。

以下是一些可能有用的信息：

有关如何避免这种情况的任何想法？这是地理中的错误吗？ GDAL？

最后，重新启动计算机，重新安装rgeos和rgdal软件包导致此代码不再崩溃R.

rgos / rgdal bug仅在加载rgdal但不加载rgeos时
