[Feature request] Run example code in Rd document

[LiNk-NY]

Hi,

I work on packages written before roxygen2 and the documentation is written in Rd format. It is often extensive and feature rich.

My issue is that there is no easy way to run code within an Rd document \examples{} section directly from the editor window (though you can run it via the Help tab) but often times I am modifying / debugging the examples in these documents.

You could say use the Rd2roxygen package but that only gets me 80% of the way there at best. It does not work well with S4, currently.

It is possible to add a hook that would recognize code in \examples{} to be runnable and sendable to the console via Ctrl + Enter?

Thank you.

Best regards,
Marcel

Reproducible RD:
