[R] rJava woes on Linux Mint 18.3 Sylvia

[J C Nash]

Is anyone else having trouble with installing rJava on Linux Mint under R 3.5?

I managed to work around troubles in Bunsenlabs Deuterium (Debian Jessie), but
it uses older libraries (openjdk-7).

Please contact off-list and I will post information when solution understood,
as, looking on the net, there seem to be a lot of people with suggestions
that don't work, or work only in some environments.
