Installing the rJava package on Ubuntu is not quite as simple as most other R packages. Some quick notes on how to do it.

  1. Install the Java Runtime Environment (JRE).
    sudo apt-get install -y default-jre
  2. Install the Java Development Kit (JDK).
    sudo apt-get install -y default-jdk
  3. Update where R expects to find various Java files.
    sudo R CMD javareconf
  4. Install the package.
    > install.packages("rJava")
  5. If you have a RStudio session open, then exit and restart it. This is important (a running RStudio session will not pick up these changes!).
