Write the provenance stamp check_inputs_supplied() reads: a character
column naming the optional inputs this build actually had, comma-separated
and sorted, or "none" when it had none. The point of the stamp is that it
is a label: unlike a total, it cannot be satisfied by arithmetic, so a
consumer can tell an absent layer from a measured zero years later and
without the producer's arguments in hand.
Usage
stamp_inputs_supplied(data, supplied, column = "inputs_supplied")
Arguments
- data
A tibble to stamp.
- supplied
Keys of the inputs that were supplied. May be empty.
- column
Name of the stamp column.
Value
data with column added or overwritten.
Examples
stamp_inputs_supplied(tibble::tibble(x = 1:2), c("ice", "water"))
#> # A tibble: 2 × 2
#> x inputs_supplied
#> <int> <chr>
#> 1 1 ice,water
#> 2 2 ice,water
stamp_inputs_supplied(tibble::tibble(x = 1:2), character())
#> # A tibble: 2 × 2
#> x inputs_supplied
#> <int> <chr>
#> 1 1 none
#> 2 2 none
