This is what I get.
"Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘ROracle’"
Then I download the tar file from CRAN and install from source using
install.packages("location", repos = NULL, type="source")
and I get:
Error: package or namespace load failed for ‘ROracle’:
package ‘ROracle’ was installed before R 4.0.0: please re-install it
I also notice Oracle has not update the package they maintain the latest is for R 3.6.0
