Description

Currently doing a build check produces lots of no visible binding for global variable [x]. Many of these are bare, unquoted column names in tidyverse pipe chains (see https://www.r-bloggers.com/2019/08/no-visible-binding-for-global-variable/), for instance:

mtcars %>%
mutate(cyl = cyl *2)

This will produce a build check warning of no visible binding for global variable 'cyl'.

The solution to avoid this is:

mtcars %>%
mutate(.data$cyl = .data$cyl *2)

I realize this is a bit more difficult ot determine where to put .data$, but it would be a nice feature.

  4. Open a pull request that references the issue number.

Research direction

The issue names no files, tests, or entry points. Start by reviewing prefixer's existing namespace-prefixing behavior and the tidyverse pipe examples described here, then determine how bare column names would be identified and where .data$ could be inserted. Done means the supported cases are defined, covered by focused tests, and no longer produce the reported build-check warnings.
