explain_print() prints the explanations behind the results
of a mapper such as grim_map(), one row after the other. It calls
explain_map() on the printed rows only.
Arguments
- data
Data frame returned by
grim_map(),grimmer_map(), ordebit_map(), or by their sequence and total-n mappers.- ...
Optionally, the rows to print, as in
dplyr::slice(): positive integers to keep rows, negative ones to drop them. Default is to print all rows.

#> GRIM test: x = 7.22, n = 32, items_averaged = 1, data_type = "integer"
#>
#> The mean was reported as 7.22, with 2 decimal places. Before rounding (assuming
#> either rounding up from 5 or down from 5), it could have been anything from
#> 7.215 to 7.225.
#>
#> The mean of 32 integers is their sum divided by 32. So the sum must be from
#> 7.215 * 32 = 230.88 to 7.225 * 32 = 231.2.
#>
#> A sum of integers is itself an integer, and 231 is in this range:
#> 231 / 32 = 7.2188, which rounds to 7.22.

#> either rounding up from 5 or down from 5), it could have been anything from

#>
#> The mean of 25 integers is their sum divided by 25. So the sum must be from
#> 4.735 * 25 = 118.375 to 4.745 * 25 = 118.625.
#>
#> A sum of integers is itself an integer, but there is no integer in this range.
#> The nearest ones are 118 and 119. They give 118 / 25 = 4.72 and
#> 119 / 25 = 4.76, which round to 4.72 and 4.76, not to 4.74.
