The first thing I do after a new RStudio install is to change Global Options to not "restore .RData into workspace at startup", and never "save workspace to .RData on exit".
I understand those defaults are those of GNU R itself, not RStudio.
RStudio already being a somewhat opinionated take on R (in my view, even more so with the tidyverse effort), would it be conceivable to change those defaults to encourage reproducibility, especially among newcomers who rely on it too much?
Edit
I just realised this has already been discussed in another topic https://forum.posit.co/t/first-line-of-every-r-script/799/12 but my question is specifically about making it the new default
