Windows下一个ROracle安装与使用

ROracle一个简短的引论:

ROracle这是R连接到接入Oracle数据库DBI（Oracledatabase interface）介面。这是基于OCI一个DBI兼容Oracle司机.

具体见说明书：http://cran.r-project.org/web/packages/ROracle/ROracle.pdf

在Linux下安装ROracle比較简单。仅仅须要用install.packages("ROracle")就可以，在windows下要通过源代码安装。

安装源文件下载地址：

http://cran.rstudio.com/src/contrib/ROracle_1.1-11.tar.gz

Win7中R安装ROracle方法：

环境变量设置：

setOCI_LIB64=E:\app\licz\product\11.2.0\dbhome_1\BIN

setOCI_INC=E:\app\licz\product\11.2.0\dbhome_1\OCI\include

set PATH=C:\ProgramFiles\R\R-3.1.1\bin\x64

注意：

假设安装的的R 64bit版本号，那么oracle client也要是64位版本号

安装步骤：

打开R

C:\Users\licz>R

>install.packages("ROracle",type = "source")
