r - 尽管 rggobi.dll 似乎可用，但无法加载

Question

我正在尝试使用clusterfly这取决于 rggobi .

我加载clusterfly并收到此错误:

> pacman::p_load(caret, clusterfly, devtools, geonames, inTrees, mclust, party, 
+                RDSTK, reshape, ROCR, RRF, sqldf, stringi, tree, xlsx)
Error in inDL(x, as.logical(local), as.logical(now), ...) :

Failed with error:  ‘package ‘rggobi’ could not be loaded’
Warning message:

clusterfly

这似乎基本上是说 rggobi.dll未位于应有的位置。

所以，我尝试直接安装并加载rgobbi并得到相同的错误:

> install.packages("rggobi")
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/rggobi_2.1.20.zip'

package ‘rggobi’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\hackr\AppData\Local\Temp\RtmpopFKT2\downloaded_packages
> require(rggobi)
Loading required package: rggobi
Error in inDL(x, as.logical(local), as.logical(now), ...) : 
  unable to load shared object 'C:/Program Files/R/R-3.2.0/library/rggobi/libs/x64/rggobi.dll':
  LoadLibrary failure:  The specified path is invalid.

我觉得这很奇怪，所以我查看了 Windows 资源管理器和文件 rggobi.dll就在它应该在的地方:

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。所以，从 rggobi 开始文件夹，我 chmod 777设置最大权限。

我仍然无法加载包，我重复了 chmod 777 的过程并试图require(gobbi)对于每个连续的文件夹级别并直接位于 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
DESCRIPTION  LICENSE  Meta       NEWS  data  help  libs
INDEX        MD5      NAMESPACE  R     demo  html
C:\Program Files\R\R-3.2.0\library\rggobi>chmod 777 libs
C:\Program Files\R\R-3.2.0\library\rggobi>cd libs
C:\Program Files\R\R-3.2.0\library\rggobi\libs>chmod 777 x64
C:\Program Files\R\R-3.2.0\library\rggobi\libs>chmod 777 i386
C:\Program Files\R\R-3.2.0\library\rggobi\libs>cd x64
C:\Program Files\R\R-3.2.0\library\rggobi\libs\x64>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 上提出问题后，Hadley Wickham 推迟了 lawremi ，他建议尝试 32 位 R，但这也导致了相同的结果。

如何使该 dll/包可供 R 使用？

我的解决方案是按照 here 中的以下说明进行操作

If you also want to install rggobi, you can install everything from within R, with the following command: source("http://www.ggobi.org/downloads/install.r")
