About the Material
This site serves as a compendium of teaching and coding material that I developed along th last couple of years. The material is based on text books (references will be given), websites (e.g., https://stats.stackexchange.com/), AI tools (e.g., ChatGPT, Blackbox AI). Many of the materials are also available as a Revealjs presentation that I usually use in teaching.

- Install the
remotespackage (Csárdi et al., 2024).
install.packages("remotes", dependencies = TRUE)- Then run the following code.
How I generated the code
installedPkgs <- as.data.frame(installed.packages()[, c("Package", "Version")]) |>
subset(subset = Package %in% pkgList[-1]) # delete base
apply(installedPkgs, 1, function(pkg) {
paste0("remotes::install_version('",
pkg[1], "', version = '",
pkg[2], "', repos = getOption(\"repos\"))")
}) |>
cat(sep = "\n\n")remotes::install_version('devtools', version = '2.4.5', repos = getOption("repos"))
remotes::install_version('dplyr', version = '1.1.4', repos = getOption("repos"))
remotes::install_version('flextable', version = '0.9.6', repos = getOption("repos"))
