r documentation on methods used by a test?

R provides a number of .tests for various applications. It is often the case that there are many methods in the literature for a test. For example, a test of a population proportion probably has at least a half dozen possible tests. Each of these has various properties, and they may make different assumptions.

The base R documentation seems to not always give much information on precisely which method is used for a test. For example ?prop.test does not mention whether the Wald method or Wilson method (or some other method) is used.

Is this information documented somewhere? How can I find out more about which methods are being used by a particular test in R?

One option is to view and dissect the source code: getAnywhere(prop.test)

While possibly tedious, it gives an unambiguous explanation for what is actually happening when you run a function.
