You need to configure R to match your Java using R CMD javareconf.
The CRAN machine uses JDK 1.9 which was the default until Java 10 was released recently. If you use something else, you have to configure R accordingly.
Also I strongly recommend using rJava 0.9-10 since it works around some issue with Java on macOS and with Java 10.

I tried installing micro plot from binary without error, but when I try to load the rJava library I was getting an error with the old Java version 151, so I accepted the Oracle offer of installing version 171 downloaded from the Java website, but I'm also seeing:
