Generate a skeleton for a new SpaDES module, a template for a documentation file, a citation file, a license file, a file, and a folder that contains unit tests information. The newModuleDocumentation will not generate the module file, but will create the other files.

newModule(name, path, ...)

# S4 method for character,character
newModule(name, path, ...)

# S4 method for character,missing
newModule(name, path, ...)



Character string specifying the name of the new module.


Character string. Subdirectory in which to place the new module code file. The default is the current working directory.


Additional arguments. Currently, only the following are supported:


Required when type = "parent". A character vector specifying the names of child modules.


Logical. Should the new module file be opened after creation? Default TRUE.


Character string specifying one of "child" (default), or "parent".


Logical. Should the new module include unit test files? Default TRUE. Unit testing relies on the testthat package.


Logical. Is module development happening on GitHub? Default TRUE.


Nothing is returned. The new module file is created at path/name.R, as well as ancillary files for documentation, citation, LICENSE, README, and tests directory.


All files will be created within a subdirectory named name within the path:

    |_ <name>/
    |_ R/               # contains additional module R scripts
    |_ data/            # directory for all included data
      |_ CHECKSUMS.txt  # contains checksums for data files
    |_ tests/           # contains unit tests for module code
    |_ citation.bib     # bibtex citation for the module
    |_ LICENSE          # describes module's legal usage
    |_        # provide overview of key aspects
    |_ <name>.R         # module code file (incl. metadata)
    |_ <name>.Rmd       # documentation, usage info, etc.


On Windows there is currently a bug in RStudio that prevents the editor from opening when file.edit is called. Similarly, in RStudio on macOS, there is an issue opening files where they are opened in an overlaid window rather than a new tab. file.edit does work if the user types it at the command prompt. A message with the correct lines to copy and paste is provided.
