You may generate a clickable table is with knitr::kable().

pick <- documentation |> select(topic, title, concept, package)

pick |>
  head() |>
  knitr::kable(col.names = NULL)

.print.via.format	Printing Utilities	Utilities	tools
Adobe_glyphs	Conversion Tables between Character Sets	Datasets available by data()	tools
AirPassengers	Monthly Airline Passenger Numbers 1949-1960	Datasets available by data()	datasets
BJsales	Sales Data with Leading Indicator	Datasets available by data()	datasets
BOD	Biochemical Oxygen Demand	Datasets available by data()	datasets
CO2	Carbon Dioxide Uptake in Grass Plants	Datasets available by data()	datasets

You may generate a searchable table with DT::datatable().

# `escape = FALSE` shows the link (defaults to showing the underlying URL)
pick |> DT::datatable(escape = FALSE)

Organization and customization

In a meta-package you may organize the documentation of the entire universe in a single place, maybe organized by package or concept (via #' @family). You may create your own custom tables with DT or other packages.

custom_table <- function(data, search = "") {
  DT::datatable(
    data,
    escape = FALSE,
    rownames = NULL,
    options = list(
      # fti =  f: filter, t: table, i: information
      dom = "fti", search = list(search = search)
    )
  )
}

• Datasets available by data()

by_concept <- filter(pick, concept == "Datasets available by data()")

by_concept |> custom_table(search = "car")

• Documentation in tools

by_package <- filter(pick, package == "tools")

by_package |> custom_table(search = "Utilities")

Presentation

In a meta-package, you may use dverse in an article, then use it to override the default Reference component.

For an example see the pkgdown Reference of dverse and follow the link to its source and see how it’s configured in _pkgdown.yml.
