6.2 Optional conventions to organise functions

• File names should be meaningful and convey which functions are defined within
• Avoid having:
  • One file per function
  • All functions in the same file
• A single .R file can have:
  • A main function and its supporting helpers like the tidyr::separate function
  • A family of related functions like the tidyr::hoist and tidyr::unnest functions
  • A very large function with lots of documentation like the tidyr::uncount function.
• For small helper functions used in functions across different files are typically stored in R/utils.R by convention (e.g spotifyr/R/utils.R)

If its hard to predict in which file a function lives, it’s time to separate your functions into more files.
