Create a new (descendant) verse of packages

Source: R/children.R
fastverse_child.Rd

Creates and installs a fully customizable descendant verse of packages that is itself extensible and inherits 90% of the functionality of the fastverse package.

Usage

fastverse_child(
  name,
  title,
  pkg,
  maintainer,
  version = "0.1.0",
  dir = ".",
  theme = c("fastverse", "tidyverse"),
  install = TRUE,
  keep.dir = TRUE,
  ...
)

Arguments

name

character. The name of the child-verse e.g. 'myMLverse'.

title

character. The title of the child-verse e.g. 'My Machine Learning Verse'.

pkg

character. A vector of core packages for the new verse.

maintainer

character. A quoted person statement giving the package maintainer. If you do not intend to substantially modify the code of the resulting source package, role = "cre" is appropriate. See Examples.

version

character. A quoted version number for the new package.

dir

character. The directory in which a source directory dir/name for the package will be created.

theme

character. Set the colour-theme for text printed to the console. The options are "fastverse" or "tidyverse".

install

logical. TRUE installs the package using install.packages(dir/name, repos = NULL, type = "source", ...).

keep.dir

logical. FALSE will remove the source directory (dir/name) again after installation.

...

further arguments to install.packages.

Value

fastverse_child returns NULL invisibly.

Details

This function creates and installs a source package according to the users specification. For that it downloads the 'child' branch of the GitHub repository, which was specifically set up to produce a new verse, unzips it into a source directory, and substitutes the user inputs into the files. The package is then installed from source, and (optionally) the source directory is removed again.

fastverse children inherit 90% of the functionality of the fastverse package: they are not permanently globally extensible and can not bear children themselves, but can be configured for projects (using a .name config file) and extended in the session. Use of this function requires an internet connection but no additional R packages (like devtools, remotes or roxygen2).
