I am Goh. I am using macOS Catalina and Java jdk-14. I had installed update version:
1. R 3.6.3
2. rJava 0.9-11.tgz
2. Weka 3.9.4 azul-zulu
3. Rplugin 1.3.27
At Weka's RConsole, I get the error message as below:
"R does not seem to be available. Check that you have the R_HOME environment variable set, R is in your path and that java.library.path property points to the JRI native library. Information on setup for different OS can be found at http://www.rforge.net/JRI "
