...emails seem to go in HTML form. Hello, This is a question that probably reveals my lack of understanding. In a C function (call it cfunc), i created a SEXP, called S, and then called R_PreserveObject on S. I returned the SEXP to the calling R function (call it rfunc). Note, I didn't call R_ReleaseObject on S. v <- .Call("cfunc") So, are the following statements correct 1. S is 'doubly' protected from the GC by being associated both with 'v' and because it has been added to the precious list (via a call to R_PreserveObject without ReleaseObject being called) 2. I...

Hi! We?ve recently come across an example where a package (minqa) creates an Rcpp Function object in a static variable. This causes R_ReleaseObject to be called by the destructor at a very late point in time - as part of the system exit function: static Function cf("c"); I?m wondering if that is considered to be ?safe?? Is the R engine supposed to stay in a state where calls to API functions are valid, even after it has shut down?...

...have a problem with the reference handling of the R objects. I've followed this strategy: every time I call a function in R and it answers me a SEXP, I called R_PreserveObject(sexp), and wrap it with a Smalltalk object. Whenever the Smalltalk object dies, I release the R object by calling R_ReleaseObject(sexp). This seems to handle well the life cycle, but makes the running process to use a growing and a never ending amount of memory. Actually, after experimenting a while, I isolated the problem to iterate over a loop which all it does is create an expresion for a number, call PreserveObject and...

Calling R_ReleaseObject in a C++ destructor is not reliable - it can be bypassed by a non-local return, such as an error. Generally in R one cannot use C++ destructors reliably for anything that the R runtime wouldn't do on its own in case of a non-local return. A destructor that calls just UNPROTECT, in a way tha...
