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:

con <- dbConnect(drv, "USER GOES HERE", "PASSWORD GOES HERE", dbname='XXX')

Hi @jssasan, when following your steps I get the following error:

Warning in install.packages : package ‘C:\Users\codrin_kruijne\Documents\ROracle\ROracle_1.3-1.zip’ is not available (for R version 3.5.1)

so I set the repos to NULL:

install.packages("C:\\Users\\codrin_kruijne\\Documents\\ROracle\\ROracle_1.3-1.zip", repos = NULL) Installing package into ‘C:/Users/codrin_kruijne/Documents/R/win-library/3.5’ (as ‘lib’ is unspecified) package ‘ROracle’ successfully unpacked and MD5 sums checked

but when I try to load it I get the following error:

library(ROracle) Loading required package: DBI Error: package or namespace load failed for ‘ROracle’: package ‘ROracle’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

so I downloaded RTools to recompile it from the source on CRAN:

install.packages("ROracle")

Installation of ROracle is a bit tricky.

1. Download ROracle package on your PC: https://www.oracle.com/database/technologies/roracle-downloads.html
   Download the tar.gz package!

2. Access the INSTALL file on ROracle sub-directory and follow the instructions. The installation differs if you have or not Oracle installed on your machine.

IMPORTANT

ROracle can't be directly installed on R4+

So, download ROracle package on your PC: https://www.oracle.com/database/technologies/roracle-downloads.html
Download the tar.gz package!

Install it on your RStudio with the following command:

install.packages('C:\Downloads\ROracle_1.3-2.tar.gz', repos = NULL, type="source")

Don't forget to correct the directory in which you've downloaded the file. This will recompile your package to version 4 of R.
