In tidyselect 1.2.0, there is a new change: Use of .data in tidyselect expressions is now deprecated to more cleanly separate tidy-select from data-masking. Replace .data$x with "x" and .data[[var]] with any_of(var) or all_of(var). I have been using .data$x inside my functions, so now all of them…

Regarding .data$x we think that select("x") and pivot_longer(c("x", y")) are so much cleaner than select(.data$x) and pivot_longer(c(.data$x, .data$y)) that we prefer to converge to a unique syntax for selections that is easy to read. Regarding .data[[var]], while it brings consistency with data-ma…

My understanding is: "tidyselect expressions" are situations where you'd use any of the {tidyselect} functions like all_of(), contains(), starts_with(), and so on. So functions like select() and across(). "data-masking" are other situations where you provide an unquoted column name to be opera…

It appears that this blog post: Programming with dplyr • dplyr has been rewritten to describe the situation. From what I can tell it was redeployed in the last couple days.

There is a blog post in preparation at tidyselect 1.2.0 by lionel- · Pull Request #600 · tidyverse/tidyverse.org · GitHub . We'll merge it soon.

It would be great to hear some reasoning behind this change. In my opinion the .data$x and .data[[x]] provided at least a somewhat consistent way to refer to the variables in the data within a package code irrespectively whether you were filtering, mutating, selecting or pulling something out of the…

And how far back does this go? Deprecation was added in tidyselect 1.2.0, but when was the new method introduced?

I wouldn't be surprised if "x" had always worked. all_of() was introduced in January 2020.

Something like all_of() is a little easier to search for. I am not sure if "x" always worked. I think I made my first proper R package around 2018 and ran into tidy-select/data-masking issues (properly setting everything up to pass R CMD check can be tricky). I had to look into this topic in more d…

yup "x" hasn't been a recommended option until recently.

Thanks, Lionel for the explanations, I see your point. I wish the blog post came online at the same time (or before) the update, that would have likely reduced the initial confusion and negativity.
