I am not able to call rJava package in R 3.0. I got the following message
rJava
R 3.0
Error: package ‘rJava’ was built before R 3.0.0: please r
I was also facing same error which was on RHEL8.1 & i resolved it as follows:
yum --enablerepo=* install java-1.8*
later i ran same command which was giving me error logs of R server.
R CMD javareconf
which turns into following output.
