R连接到Oracle - 库（ROracle）失败

它不会加载库。R连接到Oracle - 库（ROracle）失败

setwd("C:/Users/***/Desktop") 
install.packages('ROracle_1.2-1.zip', repos = NULL) 
#Installing package into ‘C:/Users/***/Documents/R/win-library/3.3 (as ‘lib’ is unspecified) 

#package ‘ROracle’ successfully unpacked and MD5 sums checked 

library('ROracle') 
#Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared object 'C:/Users/***/Documents/R/win-library/3.3/ROracle/libs/x64/ROracle.dll': LoadLibrary failure: The specified module could not be found.

我手动检查文件路径和ROracle.dll在那里。

编辑：

我有RODBC和RJDBC工作。我只是不明白为什么ROracle不会安装：

我猜想有Oracle文件需要安装，但没有一个文件非常清晰。

不知道这个特定的链接可能会有所帮助.. http://stackoverflow.com/questions/30034542/unable-to-load-any-package-in-r-unable-to-load-shared-object – theArun

我想到了这一点，这就是为什么我将目录从网络驱动器改为C：/ –

hmmm，可能是因为你在'library（“ROracle”，lib.loc =“location-to-ROracle “）'。这是否有所作为？ – theArun

为了使ROracle正确安装和加载，您应该拥有Oracle客户端64位和Windows 64位。一旦我在我的机器上安装了64位Oracle客户端，此错误就消失了。
