How to install ROracle on R 4.1.3

Time:08-12

I am attempting to install the ROracle package in RStudio so that I may connect R to my Oracle databases. I downloaded the zip file but when I run

remotes::install_local("ROracle_1.3-2.tar.gz", repos = NULL, type = "source")

I get an error :

ERROR: cannot find Oracle Client. Please set OCI_LIB64 to specify its location.

I do have Oracle Client installed on my PC. This may be an obvious answer, but my question is, how do I set OCI_LIB64 to recognize Oracle CLient's location on my PC. I am running on windows 10 and R version 4.1.3.

Have a look at the installation guide. It has the following steps for windows:

  13.Add the full path of the Instant Client to the environment variables 
     OCI_LIB64 and PATH. 

     The following steps set the variables to the PATH used in this example, 
     c:\myoreclient\instantclient_11_2. 
  1. In Windows Control Panel, select System, then click Advanced system 
     settings.
  2. On the Advanced tab, click Environment Variables. 
  3. Under System variables, create OCI_LIB64 if it does not already exist. 
  4. Set the value of OCI_LIB64 to c:\oreclient\instantclient_11_2. 
  5. Under System variables, edit PATH to include 
     c:\oreclient\instantclient_11_2.
