Dplyr warns: `…` is not empty

Question

A new warning message appeared today when printing tibbles

library(tidyverse)

mtcars %>% 
  head %>%
  as_tibble

prints

Answer 1

This question is not a duplicate of any SO question (that I can find), but it's a duplicate of an issue on tibble (tibble/#798), where the reproducible code is merely:

tibble::tibble(a = 1)
#> Warning: `...` is not empty.
#> 
#> We detected these problematic arguments:
#> * `needs_dots`
#> 
#> These dots only exist to allow future extensions and should be empty.
#> Did you misspecify an argument?
#> # A tibble: 1 x 1
#>       a
#>   <dbl>
#> 1     1

There is a patch in work (a384b33) and it appears they will push for a new CRAN release.

Your options are:

1. downgrade with

   remotes::install_version("pillar", version = "1.4.4")
   

2. install the github version of tibble with

   remotes::install_github("tidyverse/tibble")
   

3. or wait for the CRAN release (in work).
