In R (and when installing ROracle package), how do I set OCI_LIB64?

Question

In R (and when installing ROracle package), how do I set OCI_LIB64? I've downloaded Oracle Instant Client and have pointed the wd and the OCI_LIB64 to that. I have Windows 10 Enterprise. It's RStudio version 1.1.463 and R version 3.4.3.

I tried the following:

setwd('C:\\Users\\sriley03\\Documents\\')   # set to path of download (remember to escape slashes ie:  c:\\users\\etc..)
set OCI_LIB64=C:\Users\sriley03\Documents\instantclient_19_3
install.packages('ROracle_1.3-1.tar.gz', repos = NULL)

but I get the following output and errors:

> setwd('C:\\Users\\sriley03\\Documents\\')   # set to path of download (remember to escape slashes ie:  c:\\users\\etc..)
The working directory was changed to C:/Users/sriley03/Documents/ inside a notebook chunk. The working directory will be reset when the chunk is finished running. Use the knitr root.dir option in the setup chunk to change the working directory for notebook chunks.Error: unexpected symbol in "set OCI_LIB64"

Warning in install.packages :

What can I do so that I can set OCI_LIB64 properly so that I can install ROracle?

Thanks!

UPDATE (8_28_19):

I've set the OCI_LIB64 and the OCI_INC to the correct paths

Sys.setenv(OCI_LIB64="C:\\Users\\sriley03\\Documents\\oreclient_install_dir\\instantclient_19_3")
Sys.setenv(OCI_INC="C:\\Users\\sriley03\\Documents\\oreclient_install_dir\\instantclient_19_3")

But now I get the following response (even though all the required headers are in that file):

Answer 1

Try to download the SDK Package from Oracle and unzip it in your instant client folder.

set the OCI_INC to ..."instantclient_xx_x\\sdk\\include"

Then, reinstall the packages.

If you still get a failure error, try to copy all files from sdk\\include folder to your R include folder, then try again
