Hello,
This error can be a 32 bits vs 64 bits thing. R and java must have the
same architecture. If you have 64b Java installed, don't run 32b R. And
vice-versa.
Hope this helps,

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, ...)
error: unable to load shared object
'/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava/libs/rJava.so':
dlopen(/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava/libs/rJava.so,

Referenced from:
/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava/libs/rJava.so
Reason: image not found
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?

Dennis,
R does that for you already as it needs to know it for rJava too.
On my (Linux) box:
edd@rob:~$ R CMD config JAVA
/usr/lib/jvm/default-java/bin/java
edd@rob:~$ R CMD config JAVA_HOME
/usr/lib/jvm/default-java
edd@rob:~$
You could also do the equivalent of `which` or `type -p` from R:
R> Sys.which("javac")
javac
"/usr/bin/javac"
R> Sys.which("javacdoesnotexist")
javacdoesnotexist
""
R>
Hope this helps, Dirk
