Your Java is seriously old. Start by updating it (1.8.0_74 is current,
AFAIK).
I can reproduce this with the CRAN binary packages, but installing the
packages from source works for me on El Capitan (using the CRAN binary
R). So I suspect a problem with the CRAN binary package of rJava, which
seems to be hard-coded to use
/System/Library/Frameworks/JavaVM.framework and not Oracle Java.

What is going on?
What is the solution for this problem?
