👋🏼 @kuadrat , @shubhamjain15 , @RobLBaker , this is the review thread for {growR}. Just about all of our communications will happen here from now on 😄 .

As a reviewer, the first step is to create a checklist for your review by entering

@editorialbot generate my checklist

as the top of a new comment in this thread. For best results, don't include anything else in the comment!

This will create a checklist that walks through the JOSS submission requirements. As you go over the submission, please check any items that you feel have been satisfied. The first comment in this thread also contains links to the JOSS reviewer guidelines.

The JOSS review is different from most other journals. Our goal is to work with the authors to help them meet our criteria instead of merely passing judgment on the submission. As such, the reviewers are encouraged to submit issues and pull requests on the software repository. When doing so, please mention openjournals/joss-reviews#6260 so that a link is created to this thread (and I can keep an eye on what is happening). Please also feel free to comment and ask questions on this thread. In my experience, it is better to post comments/questions/suggestions as you come across them instead of waiting until you've reviewed the entire package.

We aim for reviews to be completed within about 2-4 weeks. Please let me know if you require some more time.

Please feel free to ping me (@mikemahoney218) if you have any questions/concerns.

Thank you so much for agreeing to review this submission!

👋 @kuadrat , @shubhamjain15 , and @RobLBaker , just wanted to share that I'm going to be OOO from February 2nd through the 9th (so, Friday through the end of next week). I'll be around somewhat but will be much more delayed in responding on this issue; apologies in advance!

And as always, feel free to reach out if you have any questions or concerns 😄

Regarding license (as I can see this is an unchecked box in the review checklist of @shubhamjain15 ), please have a look at the discussion that has already occurred during pre-review and links therein:

#6176 (comment)

In short: At the moment it does not seem to be possible to simultaneously satisfy CRAN's and github's conventions regarding naming and structure of license files. Since the main avenue of distribution is via CRAN, the choice has been made to follow their conventions. The conclusion in JOSS reviews for other R packages has been that this complies with JOSS (see linked comment).

Really cool work!

I missed the statement of need in the Documentation. I am assuming this is separate from the statement of need in the Software paper. Perhaps I'm overlooking it somewhere - if you could please point me in the right direction or confirm that these two statements of need are one and the same, I'd be happy to check that last box.

Dear @shubhamjain15 , @RobLBaker ,

thank you very much for your review efforts! I'm very glad to hear that the package is received mostly positively.

@RobLBaker I have extended the README with a What is this for? section on the joss branch. Once I merge this into master, the docs will be updated accordingly. It is essentially a slightly less formal rewording of relevant paragraphs in the paper. Please let me know what you think.

@RobLBaker

Hi all! My job is to help wrap up this submission and do some final checks.

First, one question for @shubhamjain15 and @RobLBaker: can you verify that you installed the software and got it to run, etc? I ask because it's a bit unusual to have reviews go this quickly and not require any issues being opened on the software repo. It happens occasionally, but just want to check in to make sure the process was clear to everyone given the circumstances. Thank you!

@RobLBaker
Copy link

Yes, I was able to download and install the package. It appears to function as claimed: I was able to recreate all of the analyses and results from the Tutorial and Calibration vignettes using the example data.

@shubhamjain15 Could you confirm the same?

Hi Kristen! Yes I was able to install the R package and use the examples in the reference manual and tutorial to test the functionality successfully.

Many thanks also to all of you for your voluntary work!

I'm happy this went so smoothly. Maybe a remark on that note: Part of what likely helped making this submission go through without many issues is the fact that the package has been published on CRAN. This means that it has already undergone a number of automated and human-overseen quality checks before being submitted to JOSS.

@kuadrat Thanks for that comment and that makes sense. I'll keep my eye out for that being a mitigating (and helpful!) factor on future reviews.
