R tip: Quick lookup tables with named vectors

The video tutorial explains how to use named vectors in R for quick lookup tables. It covers the creation of named vectors, using them for lookups, and retrieving values. The tutorial also demonstrates real-world applications, such as using FIPS codes with US Census data. Additionally, it shows how to create functions to simplify lookups and make them more generic for flexible use. The tutorial emphasizes the importance of unique names in named vectors and references Hadley Wickham's Advanced R book.
