Note: If you wish to replicate the R code below, then you will need to copy and paste the following commands in R first (to make sure you have the package and its dependencies):

install.packages("iemisc", "pander") # install the packages and their dependencies

# load the required packages install.load::load_package("iemisc", "pander")
