Especially rOpenSci's peer review process ([more here](https://devguide.ropensci.org/softwarereviewintro.html)) for R packages is fantastic.
I do most data engineering in R (RMarkdown workbooks), and most software engineering in Python/Django. It took three separate, dedicated attempts to get warm with R (pre-tidyverse, showing my age), now I'm interrupting work on an RShiny app to write this comment. The ecosystem around the tidyverse helps immensely to convert my colleague's workflows from Excel to R. Clarity and simplicity wins over purity here (you may now light your pitchforks). And NSE still breaks my brain.
