My run of the example README.md code for AnnualReports does not match the expected output. For example, when I run AnnualReports("GOOG") I get:

filing.name filing.date accession.no
1 10-K/A 2016-03-29 0001193125-16-520367
2 10-K 2016-02-11 0001652044-16-000012

rather than:

filing.name filing.date accession.no
1 10-K 2015-02-09 0001288776-15-000008
2 10-K 2014-02-12 0001288776-14-000020
3 10-K 2013-01-29 0001193125-13-028362
4 10-K/A 2012-04-23 0001193125-12-174477

If I try the roxygen example code for GetCashFlow("FB", 2016) I get the following error:

Error in fileFromCache(file) :
Error in download.file(file, cached.file, method = "auto", quiet = !verbose) :
cannot download all files

In addition: Warning message:
In download.file(file, cached.file, method = "auto", quiet = !verbose) :
URL 'https://www.sec.gov/Archives/edgar/data/1326801/000132680116000043/fb-20151231.xsd': status was '404 Not Found'

I was able to fix this error by modifying the dependency XBRL to call download.file(method = "curl"). See https://github.com/jsta/XBRL/commit/9c42ada9947aadfbc2f2fe64705cabab9eddca40.

• [x] Performance: Have any performance claims of the software been confirmed?

Documentation

• [x] A statement of need: Do the authors clearly state what problems the software is designed to solve and who the target audience is?
• [x] Installation instructions: Is there a clearly-stated list of dependencies? Ideally these should be handled with an automated package management solution.
• [x] Example usage: Do the authors include examples of how to use the software (ideally to solve real-world analysis problems).
• [x] Functionality documentation: Is the core functionality of the software documented to a satisfactory level (e.g. API method documentation)?
• [x] Automated tests: Are there automated tests or manual steps described so that the function of the software can be verified?

The automated testthat tests are extremely minimal. They only test one function. However, the manual steps described in the roxygen documentation and README.md should be sufficient to verify package functionality.

• [x] Community guidelines: Are there clear guidelines for third parties wishing to 1) Contribute to the software 2) Report issues or problems with the software 3) Seek support

At the very least you should fill out a BugReports section in the DESCRIPTION. Some package authors also choose to include a CONTRIBUTING.md. See https://github.com/ropensci/rnoaa/blob/master/CONTRIBUTING.md for an example.

Software paper

• [x] Authors: Does the paper.md file include a list of authors with their affiliations?

It seems to me that not everyone necessarily has an affiliation but going by the letter-of-the-law there is no affiliation listed in paper.md.

• [x] A statement of need: Do the authors clearly state what problems the software is designed to solve and who the target audience is?
• [x] References: Do all archival references that should have a DOI list one (e.g. papers, datasets, software)?

Miscellaneous

I'm not sure how you are building this package for CRAN and avoiding the warnings about non-standard top-level files like Read-and-delete-me and .RData. These should probably be removed or appended to Rbuildignore.

When I run goodpractice::gp() on the package using goodpractice I get the following notes:

✖ omit "Date" in DESCRIPTION. It is not required and it gets invalid
quite often. A build date will be added to the package when you
perform R CMD build on it.
✖ add a "BugReports" field to DESCRIPTION, and point it to a bug
tracker. Many online code hosting services provide bug trackers for
free, https://github.com, https://gitlab.com, etc.
✖ avoid long code lines, it is bad for readability. Also, many people
prefer editor windows that are about 80 characters wide. Try make
your lines shorter than 80 characters

R/annual_reports.R:18:1
R/annual_reports.R:20:1
R/annual_reports.R:53:1
R/backend_utilities.R:19:1
R/backend_utilities.R:42:1
... and 19 more lines

✖ avoid 1:length(...), 1:nrow(...), 1:ncol(...), 1:NROW(...) and
1:NCOL(...) expressions. They are error prone and result 1:0 if the
expression on the right hand side is zero. Use seq_len() or
seq_along() instead.

R/get_financial.R:68:17

✖ not import packages as a whole, as this can cause name clashes
between the imported packages. Instead, import only the specific
functions you need.

@arfon I ran into somewhat of a show-stopper bug with one of finreportr's dependencies (see my comment above about XBRL). It seems like a bug in a dependency is out of the present author's control. I was able to patch it myself to test the finreportr functions but the everyday user may run into frustration. How should this be handled for the review?

[sewardlee337]

@jsta - Thank you for the advice! I will start implementing some of these fixes.

[sewardlee337]

Latest updates to finreportr per @jsta's suggestions and JOSS review checklist:

• BugReports added to DESCRIPTION and Feedback section added to README.md
• MIT License full text added to LICENSE per JOSS requirement
• finreportr ver. 1.0.1 released on GitHub
• Long lines of code cut down where contextually appropriate
• Deleted top-level files Read-and-delete-me and .RData

[jsta]

@arfon I think this submission is good to go as far as acceptance pending your opinion on the XBRL (dependency of the present submission) bug described at: https://github.com/sewardlee337/finreportr/issues/1

[arfon]

@arfon I think this submission is good to go as far as acceptance pending your opinion on the XBRL (dependency of the present submission) bug described at: sewardlee337/finreportr#1

Thanks @jsta. I agree this is good to move forward.

@sewardlee337 - At this point could you make an archive of the reviewed software in Zenodo/figshare/other service and update this thread with the DOI of the archive? I can then move forward with accepting the submission.

[sewardlee337]

Thank you @jsta and @arfon!

The DOI of the software archive is http://doi.org/10.5281/zenodo.192466
