tryOrFailWithNA

The evaluation fails with <code>NA</code> by default, but it is also able to fail with other values.

Functions to design and apply tests that are anytime valid. The
functions can be used to design hypothesis tests in the prospective/randomised
control trial setting or in the observational/retrospective setting. The
resulting tests remain valid under both optional stopping and optional
continuation. The current version includes safe t-tests and safe tests of
two proportions. For details on the theory of safe tests, see
Grunwald, de Heide and Koolen (2019) "Safe Testing" <arXiv:1906.07801>,
for details on safe logrank tests see ter Schure, Perez-Ortiz, Ly and Grunwald
(2020) "The Safe Logrank Test: Error Control under Continuous Monitoring with
Unlimited Horizon" <arXiv:2011.06931v3> and Turner, Ly and Grunwald (2021)
"Safe Tests and Always-Valid Confidence Intervals for contingency tables and
beyond" <arXiv:2106.02693> for details on safe contingency table tests.
