Details

Function to run various data checks on a data table.

Checks are run separately for each part of the expression vector checks. For each single expression, the variables listed in the output are all the variables mentioned in the expression plus optional variables whose names are in the character vector id. ⁠%between% c(a,b)⁠ in expressions is printed as ⁠[a,b]⁠. The output format is plain text unless html=TRUE which also puts each table in a separate Quarto tab. See here for examples.

Value

an invisible data frame containing variables check (the expression checked) and n (the number of records satisfying the expression)
