<p>I'm just going to answer this one candidly. Yes, you are doing something wrong. Immediately: the commit history is useful to understand the context in which a bug was introduced, because it's the best context to understand the _reason_ the mistake was maybe, which is a really good way to prevent regressions. But more generally: when an entire industry has arrived at an accepted practice, you the junior developer (sorry, 5 years is _nothing_: you need to be told this too) have a chance to pick up on it.<p>Have you heard "have you played guitar for 20 years, or have you played guitar 20 times for a year?" Time only helps with accumulating wisdom if you let it.</p>

<p>You're right that I can't reproduce it like a phone camera could, and that the more precise you are the better (and it might be that with my eyes closed I'm doing something closer to addition in log-odds, like a separate comment responded), but this is super useful even coarsely. The visual affordance gives Bayes's theorem a physicality unlike any other tool I've found.</p>

<p>Seriously, though, there's one nomogram you (yes you) should know about and have it well-enough engraved in your mind's eye that you can use it with eyes closed. A nomogram for Bayes' theorem: <a href="https://www.ovid.com/journals/nejm/abstract/10.1056/nejm197507312930513~nomogram-for-bayess-theorem?redirectionsource=fulltextview" rel="nofollow">https://www.ovid.com/journals/nejm/abstract/10.1056/nejm1975...</a></p>

<p>CRAN has very different social structures and culture than other languages' package repos. CRAN _will_ pull your package from the repository if you fail to play nice with all packages, for example. This is evidently controversial, but it's accepted practice and one possible explanation for why CRAN feels more cohesive than NPM or PyPI.</p>

<p>I want to point out that you are posting from a 5-months old account (squarely within a time frame where LLM-powered accounts would be created), with an UUID-sounding username, claiming a 10-year-old professional history in the field, and using those credentials to bring up the possibility that a 14-year-old account claiming to be an MD with `md` in the username and _lots_ of comments is LLM-generated and asking for skepticism.<p>It's not particularly helpful; you could easily have done the 5 minutes of work.</p>

<p>(FWIW, I'm the technical lead on the Quarto project)<p>RMarkdown isn't going anywhere! Quarto exists to bring the RMarkdown experience that folks love to a broader set of users and contexts. It is true that we try to keep the .qmd experience in Quarto pretty close to the .rmd experience in RMarkdown, and it is true that Quarto does things that RMarkdown never will. But it's not the case that "RMarkdown is being phased out and replaced with Quarto".</p>

<p>Presumably because one of the two things are true:<p>- there's competition, and so if it's possible to rent for less than 1000-eps and still profit, someone will<p>- there's no competition, which is a cartel, the kind of thing that civilized societies ought to frown upon</p>

<p>(I imagine you agree, so this is just to expand) a secondary, insidious issue is that administrators diffuse their rules through the bureaucracy. In the case of CS, you start seeing references to csrankings in recommendation letters for grad applications, faculty applications, or even tenure letters. At that point, it can be hard to fight against it.</p>
