 * Help for a specific function can be accessed in the usual R manner: `?<function>`, where you replace `<function>` with a function name. Like this: `?group.morph.native`.
 * Run `example(<function>)` to see a live demo that uses the function `<function>`. Like this: `example(group.morph.native)`.
 * The [unit tests](./tests/testthat/) that come with this package are essentially a list of examples that illustrate how to use the functions.
