Optional issue: examples

[rrrlw]

A comprehensive example is provided in the README. However, users of the R package would also benefit from quick access to examples in the documentation itself (i.e. using the @example or @examples Roxygen tag so that it can be accessed with ?<function name>).

If adding an example within the documentation is too complex, you can simply close this issue.

Thanks for pointing this out. As someone who does access examples through the R documentation, I agree that it would be very useful to have these for the exported functions (of which there are only 3, medoutcon, est_tml, and est_onestep). I'll add these later today and update once that has been completed.

In 0980f97 of #34, I removed the exporting of the internal estimation functions est_tml() and est_onestep(), and I added an example based on the README to the eponymous function medoutcon(). Since this is satisfied (minimally), I'll go ahead and close the issue.
