Author instructions: Maximum length of abstract?

[HenrikBengtsson]

The https://journal.r-project.org/submissions.html page does not mention a maximum length of the abstract, but the example template article produced by rjtools::create_article() generates an *.Rmd file with:

abstract: >
  An abstract of less than 150 words.

Is that an official limit, because after quickly checking recently published articles, I quickly found one with 229 words in the abstract, cf. https://journal.r-project.org/articles/RJ-2023-063/.

If there's no official limit, I recommend removing the mentioning of "150 words", especially since it can be quite challenging to shrink an abstract to that length.
