R Documentation

Quick recursive arguments checks on lists and data frames

These functions are the tuned counterparts of qtest and qassert tailored for recursive checks of list elements or data frame columns.

qassertr(x, rules, .var.name)

qtestr(x, rules)

`x`	[`list` or `data.frame`] List or data frame to check for compliance with at least one of `rules`. See details of `qtest` for rule explanation.
`rules`	[`character`] Set of rules. See `qtest`
`.var.name`	[`logical(1)`] Argument name to print in error message. If missing, the name of `x` will be retrieved via `substitute`.

[logical(1)]: TRUE on success, FALSE (or a thrown exception) otherwise.

qtestr(as.list(1:10), "i+")
qtestr(iris, "n")
