Filters a result dataset for the values that failed the verification
Source:R/filters.R
filter_fails.RdFilters a result dataset for the values that failed the verification
Arguments
- res
a result data.frame as outputted from
check_data()or a ruleset- x
a dataset that was used in
check_data()- per_rule
if set to TRUE, a list of filtered data is returned, one for each failed verification rule. If set to FALSE, a data.frame is returned of the values that fail any rule.
Examples
rules <- ruleset(
rule(mpg > 10 & mpg < 30), # mpg goes up to 34
rule(cyl %in% c(4, 8)), # missing 6 cyl
rule(vs %in% c(0, 1), allow_na = TRUE)
)
res <- check_data(mtcars, rules)
filter_fails(res, mtcars)
