Overview

About

Citation File Format ('CFF') version 1.2.0 doi:10.5281/zenodo.5171937 is a human- and machine-readable file format for software citation metadata. Core utilities generate, read, write and validate Citation File Format metadata for 'R' packages.

Changes in 1.4.2
  • The JOSS paper is now linked as an external **pkgdown** article instead of being rebuilt as a package vignette.
  • **cli** messages now use more precise semantic markup, pluralization and public-facing error contexts.
  • cff_gha_update() now uses path when updating .Rbuildignore.
  • cff_read_bib_text() now rejects vectors that mix BibTeX entries with .bib file paths.
  • cff_write() now formats the inst/CITATION update message correctly.

Cite

Cite this package

Run in R for the authors' entry:

citation("cffr")

The package provides a citation file, so citation() returns the authors' own entry.

It points to 10.21105/joss.03900, 10.5281/zenodo.5171937.

The repository also keeps a CITATION.cff.
