20180603 Packages used in this chapter include RColorBrewer (Neuwirth 2022), dplyr (Wickham, François, et al. 2026), ggplot2 (Wickham, Chang, et al. 2026), qdap (Rinker 2025), qdapDictionaries (Rinker 2018), scales (Wickham, Pedersen, and Seidel 2025), stringr (Wickham 2025), tm (Feinerer and Hornik 2026), wordcloud (Fellows 2018), and rattle (G. Williams 2026).
Packages are loaded into the currently running R session from your
local library directories on disk. Missing packages can be installed
using utils::install.packages() within R. On Ubuntu, for
example, R packages can also be installed using $ wajig install r-cran-<pkgname>.
