cpp11 helps you to interact with R objects using C++ code.
Is it possible to evaluate an R function and in case of an error catch the error condition and modify it? For example I want to evaluate `log()` on `x`...
CC @jennybc and @sbearrows This is a long post, and is intended to outline a rather complex problem in a way that we can come back to in the future....
Such as it's the case for `names()`, it would be extremely convenient to have `rownames()` and `colnames()` in cpp codes. My idea (sorry that I don't enough C++) would be...

It seems there are some cases where use of unwind_protect causes issues, since there is a long jump involved, such as within constructors. It might be better to have it...
This PR adds functionality to generate C/C++ APIs which can be accessed from other packages. ## Motivation - Fast communication between packages - Manually creating the required registration and headers...
This PR attempts to force `data_p_` to always be a pointer to the "underlying" type of `SEXP data_`. Currently, this is not the case. `data_p_` currently has type `T*`, which...
