The function checks whether all the logical values returned by the expression are TRUE. The function is meant for handling all the cases that cannot be reached by using validate_cols and validate_rows functions.
Usage
validate_if(
data,
expr,
description = NA,
obligatory = FALSE,
skip_chain_opts = FALSE,
success_fun = assertr::success_append,
error_fun = assertr::error_append,
defect_fun = assertr::defect_append
)
Arguments
- data
A data.frame or tibble to test
- expr
A Logical expression to test for, e.g.
var_name > 0
- description
A character string with description of assertion. The description is then displayed in the validation report
- obligatory
If TRUE and assertion failed the data is marked as defective. For defective data, all the following rules are handled by defect_fun function
- skip_chain_opts
While wrapping data with validate function,
success_fun
anderror_fun
parameters are rewritten withsuccess_append
anderror_append
respectively. In order to use parameters assigned to the function directly set skip_chain_opts to TRUE- success_fun
Function that is called when the validation pass
- error_fun
Function that is called when the validation fails
- defect_fun
Function that is called when the data is marked as defective
