Installing the rJava package on Ubuntu is not quite as simple as most other R packages. Some quick notes on how to do it.
- Install the Java Runtime Environment (JRE).
sudo apt-get install -y default-jre
- Install the Java Development Kit (JDK).
sudo apt-get install -y default-jdk
- Update where R expects to find various Java files.
sudo R CMD javareconf
- Install the package.
> install.packages("rJava") - 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!).
Sorted!
