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
Installing rJava from the distribution packages as proposed in this askUbuntu answer also works:
sudo apt-get install r-cran-rjava
NOTE: tried from a Debian system.
