.... you would probably see a help page that has almost the same content
as the page at rdocumentation.org
(A "two sample z-test", at least as I understand such a label, is not
necessarily a test for non-inferiority. That page doesn't actually
describe the results of a calculation using the
"TwoSampleProportion.NIS" function but if you go to the code you find
it's not doing a test of any sort but rather doing an oversimplified
sample size calculation.)
You appear to not understand that R is a system of packages that are
optionally installed and loaded into the core programming environment. I
would advise that you do some self-learning about how to use R (or) that
you contract with a person who can provide the skills need to both
educate you about the statistical issues in trial design and run your
analyses for you.
