You bring up RStudio but not the R Notebooks which it supports natively (https://bookdown.org/yihui/rmarkdown/notebook.html), which IMO is a far-superior way of handling notebooks than Jupyter. (namely, the files are plain text so you can actually commit to Git without fuss)

I wrote a detailed blog post about the differences between Jupyter and R Notebooks years ago: https://minimaxir.com/2017/06/r-notebooks/
