Dirk
I am now more confused (and I appreciate your help in sorting this out).
I executed
require(“rJava”)
and received the following error:
> Error: package or namespace load failed for ‘rJava’:
> .onLoad failed in loadNamespace() for 'rJava', details:
> call: dyn.load(file, DLLpath = DLLpath, ...)

Java is definitely installed on this machine — from a terminal:
PET513> Java -version
java version "13.0.1" 2019-10-15
Java(TM) SE Runtime Environment (build 13.0.1+9)
Java HotSpot(TM) 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)
It appears that the problem relates to version # — I have 13.03.1 installed
whereas R is looking for 11.0.1
Any idea how to fix this?
