Answer 1

I had the exact same problem, and I have just resolved it thanks to a conference with some very kind and helpful Oracle personnel.

We need to include the following line in /etc/rstudio/rserver.conf file (which by default is empty):

rsession-ld-library-path=/usr/lib64/R/lib:/u01/app/oracle/product/12.1.0.2/dbhome_1/lib

i.e. the R & Oracle home directories:

$ echo $R_HOME
/usr/lib64/R
$ echo $ORACLE_HOME
/u01/app/oracle/product/12.1.0.2/dbhome_1

You have to restart the RStudio server after modifying the configuration file.

I have checked this only with RStudio server, so not sure if it is necessary for RStudio Desktop, too...

See here for more details (although it refers to Oracle R Enterprize, it is also applicable to vanilla R).
