chk (version 0.10.0)

chk_all_equivalent: Check All Equivalent

Description

Checks all elements in x equivalent using

length(x) < 2L || all(vapply(x, vld_equivalent, TRUE, y = x[[1]], tolerance = tolerance))

Usage

chk_all_equivalent(x, tolerance = sqrt(.Machine$double.eps), x_name = NULL)
vld_all_equivalent(x, tolerance = sqrt(.Machine$double.eps))

Value

The chk_ function throws an informative error if the test fails or returns the original object if successful so it can used in pipes.

The vld_ function returns a flag indicating whether the test was met.

Arguments

x

The object to check.

tolerance

A non-negative numeric scalar.

x_name

A string of the name of object x or NULL.
