Get memory address of an R data frame
Hello,
I would like for my C function to be able to manipulate some values stored in an R data frame.
To achieve this, a need the (real) memory address where the R data frame stores its data (hopefully in a contiguous way). Then, from R, I call the C function and passing this memory address as a parameter.
The question: how can we get the memory address of the R data frame?
Thank you!
L.
