Check Whole Numeric

Checks if integer vector or double equivalent using

is.integer(x) || (is.double(x) && vld_true(all.equal(x, as.integer(x))))

Usage

chk_whole_numeric(x, x_name = NULL)

vld_whole_numeric(x)

Arguments

x

The object to check.

x_name

A string of the name of object x or NULL.

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.
