Thank you Luke. That is why I don't use Rf_inherits but INHERITS which does not allocate, provided in the email body. I cannot do similarly for S4 classes, thus asking for some API for that.

Thank you Luke for prompt reply. Is it possible then to request a new function to R C API "message" that would equivalent to R "message" function? Similarly as we now have C "warning" and C "error" functions.

I am not using the C API from a package but with an embedded R. Why have it declared in the include/ if it cannot be accessed then?

...or SET_NAMED functions even though this has been discouraged for some time. For now these will not produce errors but also not do anything useful. They will probably be removed before R 4.0.0 is released, so you should look at why you are using them and adjust accordingly. Best, luke -- Luke Tierney Ralph E.

I am excited to learn that Prof. Tierney is bringing to us compiled R. I would like to learn when it will be available. This information will be useful in scheduling some of my projects. Thanks.

I have committed a change to R-devel that addresses this. To be on the safe side I need to run some more extensive tests before deciding if this can be ported to the release branch for R 3.5.0.
