qassertr: Quick recursive arguments checks on lists and data frames

Description

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

Usage

qassertr(x, rules, .var.name)
qtestr(x, rules)
qexpectr(x, rules, info = NULL, label = NULL)

Arguments

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.

info

label

[character(1)] Same as .var.name, but passed down to expect_that.

Value

• See qassert.

Examples

# All list elements are integers with length >= 1?
qtestr(as.list(1:10), "i+")

# All list elements (i.e. data frame columns) are numeric?
qtestr(iris, "n")

# All list elements are numeric, w/o NAs?
qtestr(list(a = 1:3, b = rnorm(1), c = letters), "N+")

# All list elements are numeric OR character
qtestr(list(a = 1:3, b = rnorm(1), c = letters), c("N+", "S+"))
