[SOLVED] How to include Authors@R in the manual of R package?

How to include Authors@R in the manual of R package?

I have the following description file as part of my R package

Package: blah
Title: What the Package Does (one line, title case)
Version: 0.0.0.9000
Authors@R: person("Jon", "Snow", email = "jon.snow@jonsnow.ac.uk", role = c("aut", "cre"))
Description: What the package does (one paragraph).
Depends: R (>= 3.5.1)
License: What license is it under?
Encoding: UTF-8
LazyData: true
RoxygenNote: 6.1.0.9000

I have documented my code and would like to produce a manual that accompanies it. In a previous post, people have mentioned using the command R CMD Rd2pdf <work directory> and I managed to produce a manual.

The issue is that in my manual, the bit before R topics documented does not show the authors but everything else. I have installed packages such as devtools, knitr, roxygen2 and testthat. Any advice would be highly appreciated.

Solution

If you want to include multiple authors, you have to wrap all persons in c().

See the DESCRIPTION of sf for example, which looks something like this:

Authors@R: 
  c(person(given = "Edzer",
           family = "Pebesma",
           role = c("aut", "cre"),
           email = "edzer.pebesma@uni-muenster.de",
           comment = c(ORCID = "0000-0001-8049-7069")),
    person(given = "Jeroen",
           family = "Ooms",
           role = "ctb",
           comment = c(ORCID = "0000-0002-4035-0289")),
    person(given = "Kirill",
           family = "Müller",
           role = "ctb"))

If there is only one author, you can simply write:

Author: Lax Chan
