Reproducible examples

• reprex (noun)
• reprex
• reprex::reprex()

Why reprexes?

Easier to talk about code that:

• Actually runs

• I don't have to run

• I can easily run

reprex

library(tidyverse)
count(diamonds, colour)

Customizing reprex()

reprex(
  x = mean(rnorm(100)),
  si = TRUE
)

reprex(
  x = mean(rnorm(100)),
  venue = "r"
)

reprex(
  x = {
if (TRUE) "true branch" else {
  "else branch"
}
  },
  style = TRUE
)

Reprex do's and don'ts

• Ensure the example is fully reproducible
• Use the smallest, simplest, most built-in data possible
• Include commands on a strict "need to run" basis
• Consider including "session info"
• Use good coding style to ensure the readability of your code by other human beings
• Ensure portability of the code
