Install R and RStudio with RJava, RGL, JGR, etc.

# Install dependencies:
sudo apt libssl-dev mesa-common-dev
# for rgl https://stackoverflow.com/a/52840933
sudo apt install libftgl2 libcgal-dev libglu1-mesa-dev libglu1-mesa-dev libx11-dev libfreetype6-dev

# Install R

## Fix Java path
sudo R CMD javareconf

## Apply this fix: https://stackoverflow.com/a/52110207


# Install utils : JGR, Deducer, etc.
update.packages(ask = FALSE, checkBuilt = TRUE)
install.packages(c("JavaGD","JGR","Deducer"))

install_version("rJava", version = "0.9-8")
