Scope

• Please indicate which category or categories from ourpackage fit policies this package falls under: (Please check an appropriate box below. If you are unsure, we suggest you make a pre-submission inquiry.):

  • data retrieval
  • data extraction
  • data munging
  • data deposition
  • workflow automation
  • version control
  • citation management and bibliometrics
  • scientific software wrappers
  • field and lab reproducibility tools
  • database software bindings
  • geospatial data
  • text analysis

• Explain how and why the package falls under these categories (briefly, 1-2 sentences):

Package yfR retrieves and organizes data fromYahoo Finance, a large repository for stock price data.

• Who is the target audience and what are scientific applications of this package?

Target audience are students, researchers and industry practioneers in the field of Finance and Economics.

• Are there other R packages that accomplish the same thing? If so, how does yours differ or meetour criteria for best-in-category?

Package yfR is the second and backwards-incompatible version ofBatchGetSymbols, also developed by me. My plan is to first deprecate BatchGetSymbols and later remove it from CRAN and archive it in Github.

Moreover, there are other packages, such asquantmod, that downloads data from Yahoo Finance, but none with similar features to yfR and BatchGetSymbols.

• (If applicable) Does your package comply with ourguidance aroundEthics, Data Privacy and Human Subjects Research?

Yes.

• If you made a pre-submission inquiry, please paste the link to the corresponding issue, forum post, or other discussion, or@tag the editor you contacted.

• Explain reasons for anypkgcheck items which your package is unable to pass.

Unfortinately, I was not able to run pkgcheck locally as I was unable to install (or make) dependency ctags in my Linux Mint 20.3 machine. Nonetheless, I read through and followed all guidelines available in themanual.
