[R] R and Java 10 ➜ rJava not able to build

[Jeff Newmiller]

I am not a Mac user, but I do use Linux and I would recommend not running R with sudo unless you are an admin ninja. That defensive practice would render the answer to your question moot.

It is possible that your problem may have started with inappropriate use of sudo in configuring java, but configuring Java is not on-topic here.
