Document a Universe of Packages.

dverse

The goal of dverse is to document a universe. It creates a data frame containing the metadata associated with the documentation of a collection of R packages. It allows for linking topic names to their corresponding documentation online.

If you have a meta-package, dverse helps you to create a comprehensive reference for its website.

Installation

Install from CRAN:

install.packages("dverse")

or get a development version from GitHub:

# install.packages("pak")
pak::pak("maurolepore/dverse")

Motivation

The Tidyverse popularized the idea of a “universe of packages.” The typical universe has a meta-package that centralizes access to functions and data across all its packages. For example, with library(tidyverse) the tidyverse meta-package centralizes access to the functions in dplyr, ggplot2, and several other packages in the Tidyverse universe.

However, meta-packages typically don’t centralize documentation. For example, the tidyverse website only shows the documentation for the tidyverse meta-package itself but does not show the documentation for dplyr, ggplot2, and other packages in the Tidyverse.

The dverse package solves this problem. It creates a data frame containing the metadata associated with the documentation of any set of packages. This data frame can be easily used to generate the universe-wide reference for the meta-package website, for example using pkgdown.

Example

document_universe() creates a data frame with documentation metadata of one or more packages.

library(glue)
library(tibble)

packages <- c("glue", "tibble")
url_template <- "https://{package}.tidyverse.org/reference/{topic}.html"
docs <- dverse::document_universe(packages, url_template)
