"R users who want to improve their programming skills and understanding of the language. It should also be useful for programmers coming to R from other languages, as help you to understand why R works the way it does."

Holy Grail of Building R-Packages
“R Packages” by Hadley Wickham and Jennifer Bryan
Very in-depth, discusses all the fundamentals of building a package and introduces useful tools (devtools, usethis)

Brief Overview of building R-packages
Mastering Software Development in R: Chapter 3 Building R Packages
Part of a book on software development in R (highly recommend the entire book to anyone working in R)

Bioconductor Developer Book
Bioconductor Packages: Development, Maintenance, and Peer Review
If you are looking to build a package for Bioconductor, I heavily recommend going through these guidelines before starting as they have a rigorous approval process
