## Commenting

Use `#` signs to comment. Comment liberally in your R scripts. Anything to the
right of a `#` is ignored by R. Comments remind yourself of what certain functions you write do, and it helps others understand their purpose without having to read the code. Start your comments with a `#` signs, which R takes as the sign to ignore anything to the right of it when running the code. Also remember that expressive naming of functions, arguments and variables, as well as [`#'`\-prefixed roxygen documentation](08-making-packages-R.Rmd), document your code. Consider free-form, #-comments as a last resort.
