[R-pkg-devel] ORCID ID finder via tools::CRAN_package_db() ?

# 
Has anybody written a quick helper function that extracts the Authors at R field
from tools::CRAN_package_db() and 'stems' it into 'Name, Firstname, ORCID'
which one could use to look up ORCID IDs at CRAN? The lookup at orcid.org
sometimes gives us 'private entries' that make it harder / impossible to
confirm a match. Having a normalised matrix or data.frame (or ...) would also
make it easier to generate Authors at R.

Cheers, Dirk

Dear Dirk,

Maybe checklist:::author2df() might be useful. It is an unexported function
from my checklist package. It converts a person() object to a dataframe.
https://github.com/inbo/checklist/blob/5649985b58693acb88337873ae14a7d5bc018d96/R/store_authors.R#L38

df <- tools::CRAN_package_db()
lapply(
  df$`Authors at R`[df$Package  %in% c("git2rdata", "qrcode")],
  function(x) {
    parse(text = x) |>
      eval() |>
      vapply(checklist:::author2df, vector(mode = "list", 1)) |>
      do.call(what = rbind)
  }
)

That's a very nice start, thank you. (Will also look more closely at
checklist.)  It needs an `na.omit()` or alike, and even with that `rbind`
barked a few entries in (i = 19 if you select the full vector right now).

But definitely something to play with and possibly build upon. Thanks!  (And
the IDs of Floris and you were two of the ones I 'manually' added to a
DESCRIPTION file ;-)

Hi Dirk,

Happy to help. I'm working on a new version of the checklist package. I
could export the function if that makes it easier for you.

Best regards,

Thierry

Would be happy to help / iterate. Can you take a stab at making the
per-column split more robust so that we can bulk-process all non-NA entries
of the returned db?

Dirk et al,

Sorry for not replying any sooner :-)

I think for now you could use something like what I attach below.

Not ideal: I had not too long ago starting adding orcidtools.R to tools,
which e.g. has .persons_from_metadata(), but that works on the unpacked
sources and not the CRAN package db.  Need to think about that ...

We need something like that too as I fat-fingered the string 'ORCID'. See
fortune::fortunes("Dirk can type").

Will the function below later. Many thanks for sending it along.

As I think that should be

rather than

I think that has become both recursive and demonstrating excellent 
test-retest stability!? Oh boy do I know that issue!

Yes, thank you. I also failed to run that post through CI and testing before
sending.  Doing too many things at once...

Very nice. Resisted my common impulse to make it a data.table for easy
sorting via keys etc.  After running your code the line

   head(with(a, sort_by(a, ~ family + given)), 100)

shows that we need a bit more QA as person entries are not properly split
between 'family' and 'given', use the URL and that we have repeats.
Excluding those is next.

Right.  One should canonicalize the ORCID (having the URLs is from being
nice) and then do unique() ...

The variant attaches drops the URL and does unique.

Hmm, the ones in

  head(with(a, sort_by(a, ~ family + given)), 100)

without a family look suspicious ...

Looking into one particular example,

https://github.com/seabbs/idmodelr/blob/master/DESCRIPTION

this appears to be the authors' fault:

Authors at R: c(
     person(given = "Sam Abbott",
            role = c("aut", "cre"),
            email = "contact at samabbott.co.uk",
            comment = c(ORCID = "0000-0001-8057-8037")),
     person(given = "Akira Endo",
            role = c("aut"),
            email = "akira.endo at lshtm.ac.uk",
            comment = c(ORCID = "0000-0001-6377-7296")))

   Maybe CRAN should start checking for missing 'family' fields in 
Authors at R ... ???

Dear Ben,

This is as simple as setting mandatory given and family fields.
checklist::check_description() ensures that given and family are set unless
the role is "cph" or "fnd". Allowing for organisations to be listed with
only the given field.

The 0.4.1 branch of checklist
<https://github.com/inbo/checklist/tree/0.4.1> now
exports the author2df() function which now can handle objects of call
person, list, logical (NA) and NULL. Feedback is welcome.

library(checklist)
df <- tools::CRAN_package_db()
vapply(
  df$`Authors at R`[df$Package %in% c("git2rdata", "A3", "digest", "abe")],
  function(x) {
    parse(text = x) |>
      eval() |>
      list()
  },
  vector(mode = "list", 1)
) |>
  unname() |>
  author2df()

Nice. Alas, some of us default to r-release as the daily driver and then

  Error in unname(tools:::.ORCID_iD_canonicalize(o)) : 
    object '.ORCID_iD_canonicalize' not found

Will play with my 'RD' which I keep approximately 'weekly-current'. Quick

Meanwhile, I am close to committing a change to R-devel which adds
tools::CRAN_authors_db() with docs

  \code{CRAN_authors_db()} returns information on the authors of the
  current CRAN packages extracted from the \samp{Authors at R} fields in
  the package \file{DESCRIPTION} files, as a data frame with character
  columns giving the given and family names, email addresses,
  \abbr{ORCID} identifier, roles, and comments of the person entries,
  and the corresponding package.

Once make check-all is done ...

-k

PS.  Sorry about tools:::.ORCID_iD_canonicalize(), had run into the same
issue when building the authors db on the CRAN master (which uses
current R release ...)

As simple as adding

  .ORCID_iD_canonicalize <- function (x) sub(tools:::.ORCID_iD_variants_regexp, "\\3", x)

and making the call (or maybe making it a lambda anyway ...)

  oid = unname(.ORCID_iD_canonicalize(o)))

After adding

  a <- sort_by(a, ~ a$family + a$given)

the first 48 out if a (currently) total of 6465 are empty for family.

  > sum(a$family == "")
  [1] 48

Rest is great!
