Java

For the R packages ReporteRs (also rJava and xlsx), need to get java installed in the right way.

Here are Mac instructions:

On linux, I did:

sudo apt update
sudo apt install default-jre default-jdk

And then in my ~/.bashrc file, I included

export JAVA_HOME="/usr/lib/jvm/default-java"

I also needed to run

R CMD javareconf

Alternatively, to install the latest version

sudo apt install openjdk-25-jdk openjdk-25-jre
