Ah, perfect (reg.finalizer). Thanks. T.

(Tried this query on r-help with no luck, maybe someone here can help?) I would like to call the 'RFinalizerEx' function that appears in Rinternals.h using ".Call". It worked for me in the past, but now I get an error message something like: 'call function name not in call table'. I'm using the 1.6.1 rpm from CRAN. Anyone know what's going on? Thanks.
I don't see a function of that name in there? $ find BUILD/include -name *.[ch] | xargs grep FinalizerEx BUILD/include/Rinternals.h:void R_RegisterFinalizerEx(SEXP s, SEXP fun, Rboolean onexit); BUILD/include/Rinternals.h:void R_RegisterCFinalizerEx(SEXP s, R_CFinalizer_t fun, Rboolean onexit); However, you can't find those with is.loaded either. I'm getting rusty on the linker issues, but I don't think you can expect to call just any function in the C level interface using .Call. (Perhaps we need another section in "Writing R Extensions"? -- I couldn't find a clear indication of what, if any, functions are getting exported to .C and friends from the main binary and by which mechanism.) Notice the existence of reg.finalizer(), which may be the functionality you were looking for in the first place. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
