Exploring the now package to write code without any obsolete functions

The now package

Thanks to Antoine Fabri’s post, I discovered the package now which allows to remove deprecated, superseded, defunct, questioning or reexported functions from tidyverse packages.

The README.md file is explains how we can see how many functions remain after having removed all the deprecated, superseded, defunct, questioning or reexported ones. See this table which comes from the README.md .

library(tidyverse)

before <- sapply(tidyverse_packages(), \(pkg) length(getNamespaceExports(pkg)))

now::clean_up_tidyverse(
  c(
    "experimental", "superseded", "deprecated", "defunct", "questioning",
    "reexports"
  )
)

after <- sapply(tidyverse_packages(), \(pkg) length(getNamespaceExports(pkg)))

left_join(enframe(before, value = "before"), enframe(after, value = "after"),
  by = "name"
) |>
  filter(after != before) |>
  mutate(keep_ratio = sprintf("%2.0f%%", 100 * after / before)) |>
  arrange(keep_ratio) |>
  knitr::kable()
