from a past post. How to install ROracle package on Windows 7?

Download binary from oracle: http://www.oracle.com/technetwork/database/database-technologies/r/roracle/downloads/index.html

The run the following command in r, substituting the file path:

setwd('xxxxx')   # set to path of download
install.packages('ROracle_1.2-1.zip', repos = NULL)
Then load the library and use the package - you may have to change XXXX to whatever is in your TNS Names:

library('ROracle')
drv <- dbDriver("Oracle")
con <- dbConnect(drv, "USER GOES HERE", "PASSWORD GOES HERE", dbname='XXX')
test connection:

dbReadTable(con, 'DUAL')

was able to install from source and download the pre compiled addin directly from oracle

Are you on CentOS7?

I've grappled the issue for a long while and have had to document my findings here. But the bird's-eye view of the process is:

Install oracle instant-client with yum.
Set the OCI_LIB and OCI_INC environment variables.
Run ldconfig.
Call install.packages('ROracle')

It also helps to use a proper package management tool like packrat so that you never have to go through this process ever again.
