Romain François commented on ARROW-3818:
----------------------------------------

this is no longer needed: 

{code:r}
library(arrow, warn.conflicts = FALSE)

batch <- record_batch(x = 1:2, y = 1:2)
tab <- table(batch, batch, batch)
tab
#> arrow::Table
as_tibble(tab)
#> # A tibble: 6 x 2
#>       x     y
#>   <int> <int>
#> 1     1     1
#> 2     2     2
#> 3     1     1
#> 4     2     2
#> 5     1     1
#> 6     2     2

# from a list of rbs
batches <- list(batch, batch, batch)
tab <- table(!!!batches)
tab
#> arrow::Table
as_tibble(tab)
#> # A tibble: 6 x 2
#>       x     y
#>   <int> <int>
#> 1     1     1
