)An agent object of class ptblank_agent.
The column (or a set of columns, provided as a character vector) to which this validation should be applied.
expressions used for mutating the input table before
proceeding with the validation. This is ideally as a one-sided R formula
using a leading ~. In the formula representation, the tbl serves as the
input data table to be transformed (e.g.,
~ tbl %>% dplyr::mutate(col = col + 10). A series of expressions can be
used by enclosing the set of statements with { } but note that the tbl
object must be ultimately returned.
An optional, text-based description for the validation step.
A list containing threshold levels so that the validation step
can react accordingly when exceeding the set levels. This is to be created
with the action_levels() helper function.
A ptblank_agent object.
