If this pull request is not ready for review (including passing the 'Run Benchmark' tests), I will open this PR as a draft (click on the down arrow next to the 'Create Pull Request' button).

GitHub Actions 'Run Benchmark' tests are passing on this base branch of this pull request (include link to passed test: ).

This submission was written on a forked copy of SingleCellOpenProblems.

This submission adds a new feature not listed above.

This submission fixes a bug (link to related issue: ).

This submission adds a new Docker image.

This behaviour was fixed in 5.0.5, but then parameterized tests stop recognising the test function signature. Rationale for rewriting decorator calls is that decorator didn't pass test keyword argument correctly (see here).

Please, let me know if you want this to be set only for test mode, or if this is ok for full benchmark as well.

Notice that my numpy array is created using R list objects in a manner analogous to Python lists: np.array(, ]). Importing Python modules with reticulate::import() produces the same behaviour: np <- import('numpy') Notice that to use the def from the Python session embedded in my R session, I had to ask for it using py$object_name вЂ“ this is different than if I sourced a Python file directly, in which case the Python function becomes available directly in the R session (ie I donвЂ™t need py$). # 10 ICE Intercontinental Exchange Inc 2.18% I now have the get_holdings function in my R session, and can call it as if it were an R function attached to the py object that reticulate creates to hold the Python session: library(tidyverse)

I have a Python script, download_spdr_holdings.py for scraping ETF constituents from the SPDR website: '''download ETF holdings to csv file'''Дf = pd.read_csv(url, skiprows=1).to_csv(f': import pandas as pdДf = pd.read_csv(url, skiprows=1, usecols=) ItвЂ™s trivial and we could replace this Python script with R code in no time at all, but IвЂ™m sure you have more complex Python scripts that you donвЂ™t feel like re-writing in RвЂ¦ Scraping ETF Constituents with Python from R Studio

Ability to bind to different Python environmentsДЇor me, the main benefit of reticulate is streamlining my workflow.

Direct object translation (eg pandas.DataFrameвЂ“ ame, numpy.arrayвЂ“ matrix etc).

Ability to call Python flexibly from within R:.

Some useful features of reticulate include: Thanks to the reticulate package ( install.packages('reticulate')) and its integration with R Studio, we can run our Python code without ever leaving the comfort of home. Other data scientists who work in bigger teams would likely have even more of a need to switch contexts regularly. Tools for doing this sort of thing in RвЂ™s tidyverse are really maturing, so IвЂ™m doing more and more of this without leaving R.Д«ut I also have a pile of Python scripts that I used to lean on, and it would be nice to be able to continue to leverage that past work. But, until recently, IвЂ™d tend to reach for Python for anything more general, like scraping web data or interacting with an API. Personally, I prefer to use R for data analysis.

Modern data science is fundamentally multi-lingual.ДЄt a minimum, most data scientists are comfortable working in R, Python and SQL many add Java and/or Scala to their toolkit, and itвЂ™s not uncommon to also know oneвЂ™s way around JavaScript.
