虽然它似乎可用,但无法加载rggobi.dll

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)

这似乎基本上说rggobi.dll不在它应该的位置.

所以,我尝试直接安装和加载rgobbi并得到相同的错误：

我发现这很奇怪,所以我在Windows资源管理器中看一下,文件rggobi.dll正好在它应该是的地方：

在尝试加载它之后,我的下一个想法是可能存在某种文件权限问题.所以,从rggobi文件夹开始,我chmod 777设置最大权限.

我仍然无法加载包,我重复chmod 777的过程,并尝试为每个连续的文件夹级别和直接在rggobi.dll上要求(gobbi)：

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推迟到lawremi,他建议尝试32位R,但这也导致了同样的结果.

如何让这个dll /包可用于R？
