[R] Citing R/Packages Question

[Jim Lemon]

Most common styles (e.g. APA, Harvard) include the date of access for an 
electronic reference. While this may be an artifact of history, both 
reviewers and editors are justified in asking authors to adhere to the 
style used in a particular journal. That said, I don't see why Nature or 
any other journal would refuse to include a reference that was properly 
formatted.
