Suggest a range check

write_domain_check(d, vars = names(d), only_positive = TRUE, file = stdout())

suggest_domain_check(d, vars = names(d), only_positive = TRUE)

Arguments

d

data.frame, used to generate the checks

vars

character optionally the subset of variables to be used.

only_positive

if TRUE only numerical values for positive values are included

file

file to which the checks will be written to.

Value

suggest_domain_check returns validate::validator() object with the suggested rules. write_domain_check returns invisibly a named list of checks for each variable.

Examples

data(SBS2000, package="validate")
