distinct not working with lists

See reprex below. Possible context in Rdatatable/data.table#3332

library(grid)

Just to confirm, it works with dplyr:

library(grid)
library(ggplotify)

p1 <- as.grob(~barplot(1:10))

library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union

tibble(
  a = rep(1, 2),
  grob = rep(list(p1), 2)
) %>% 
  distinct(a, grob)
#> # A tibble: 1 × 2
#>       a grob   
#>   <dbl> <list> 
#> 1     1 <gTree>

All set - thanks for catching this!

# install.packages("pak")
# pak::pak("markfairbanks/tidytable")
library(tidytable)

df <- tidytable(x = 1, l = list(1, 1))

distinct(df)
#> # A tidytable: 1 × 2
#>       x l        
#>   <dbl> <list>   
#> 1     1 <dbl [1]>
