Although you *can* do this in one step with a word boundary:

str_split("A,B,C, D", ",\\b")

Yeah, just realized I misread the request. 😆

Oh, lol, and I just realized I totally misread it.

str_split(string, "\\s*,\\s*") will treat any combination of space and a comma as the delimiter.

Column | Food critic Tom Sietsema is stepping down — and dropping his anonymity

After a quarter-century of reviewing restaurants, donning disguises and turning down photos, The Post’s food critic is ready for his next course.

See, to me it seems pretty harmless. The use cases that baffle me are the ones that could get you sued for malpractice or disbarred if it screws up.

Oh, see this totally makes sense to me. Presumably they read all the guidebooks and travel websites, and the stakes are generally pretty low if it gives bad suggestions.

Terrific piece from @gelliottmorris.com this morning.

Whenever you ask if something “might” happen or “may” be necessary, it’s very easy for respondents to think of scenarios where the answer is yes, no matter how unlikely.

Why most polls overstate support for political violence

Misperceptions about the popularity of violence increase public support for it — but you can help change that.

Depending on how you plan to distribute it, neither would require you to collect anything identifying (like email addresses), although if you are planning to post a public link, there will probably be a lot of spam/bots no matter what.

SurveyMonkey and Alchemer are both decent with the former being easier but less flexible and the latter costing a bit more. Qualtrics is very expensive unless you work at a university and get it for free.

The US Supreme Court returns today for its new term, two decades after John Roberts became chief justice. As this chart shows, public views of the court are much more negative – and far more politically divided – than 20 years ago. www.pewresearch.org/short-reads/...

If you must, search for “bigot neuron”, but don’t say you weren’t warned.

This is 100% correct. At this point I would pay extra to get rid of copilot.

If you’re lucky, you have either blocked or been blocked by one or more of the relevant parties.

Oh I meant “deep cut” in the sense that he was referencing an obscure bit of internet lore from 2008 but that works too.

That’s a pretty deep cut but also yes.

Agree about target trials. I guess I see Pearl and Robins as connected they’re coauthors some papers related to DAGS and confounding. But you’re right that Robins uses counterfactuals. It’s messy.

Published online. It was originally published in 2000.

I don’t know that you do actually *need* counterfactuals. Dawid has what seems to me to be a pretty compelling approach based on predictions. I think it’s more a question of preference/emphasis.
