无法加载 rggobi.dll，尽管它似乎可用

问：

我正在尝试使用取决于 .clusterflyrggobi

我加载并收到此错误：clusterfly

这似乎基本上说它不在它应该在的地方。rggobi.dll

因此，我尝试直接安装和加载并收到相同的错误：rgobbi

我觉得这很奇怪，所以我在 Windows 资源管理器中看了一下，文件就在它应该在的位置：rggobi.dll

在再次尝试加载它失败后，我的下一个想法是可能存在某种文件权限问题。因此，从文件夹开始，我设置最大权限。rggobichmod 777

我仍然无法加载包，我重复了该过程并尝试为每个连续的文件夹级别直接加载：chmod 777require(gobbi)rggobi.dll

C:\Program Files\R\R-3.2.0\library>chmod 777 rggobi
C:\Program Files\R\R-3.2.0\library>cd rggobi
C:\Program Files\R\R-3.2.0\library\rggobi>ls

rggobi.dll  symbols.rds
C:\Program Files\R\R-3.2.0\library\rggobi\libs\x64>chmod 777 rggobi.dll

最后，在 Github 上打开一个问题后，Hadley Wickham 听从了 lawremi，他建议尝试 32 位 R，但这也导致了相同的结果。

如何使此 dll/包可用于 R？
