chkor_vld: Chk OR

In chk: Check User-Supplied Function Arguments

Chk OR

Description

Chk OR

Usage

chkor_vld(..., x_name = NULL)

Arguments

...	Multiple vld_ calls. A common mistake is to pass chk_ calls. chkor_vld() is relatively slow. If at all possible use chk_null_or() or first test using the individual vld_ functions and then call chkor_vld() to generate an informative error message.
x_name	A string of the name of the object to use in the error message or NULL. If a string it is passed to each of the chk_ calls so that the error message refers to x_name rather than the deparsed vld_ arguments.

Value

An informative error if the test fails.
