...lot of objects are protected and/or external code is protecting/releasing objects through a FIFO proxy. > Reading the source (below, from memory.c) I think not, but some > confirmation would help. I understand the code in memory.c like an object preserved twice needs to be freed twice: R_PreciousList is just a (linked) list, and "R_PreserveObject(object)" adds the object to the beginning of the list while "R_ReleaseObject(object)" removes the first "object" found from the list. > void R_PreserveObject(SEXP object) > { > R_PreciousList = CONS(ob...

...s wondering if there was documentation about it. In particular, if we preserve the same SEXP twice (or more), should we implement some sort of reference counting ? Reading the source (below, from memory.c) I think not, but some confirmation would help. void R_PreserveObject(SEXP object) { R_PreciousList = CONS(object, R_PreciousList); } static SEXP RecursiveRelease(SEXP object, SEXP list) { if (!isNull(list)) { if (object == CAR(list)) return CDR(list); else CDR(list) = RecursiveRelease(object, CDR(list)); } return list; } void R_ReleaseObject(SEXP object) { R_Pre...

Hello. This is my first post to the list, so first I'd like to thank everybody for making and mantaining such a great product as R. I'm writting a native binding to R from Dolphin Smalltalk. I've followed up the examples of the documentation showing how to run R embedded, and I got it partially working. However, I have a problem with the reference handling of the R objects.
