...that looks like this (inspired from do_serializeToConn) : SEXP serialize_to_connection( SEXP xp, SEXP connection ){ Rconnection con ; struct R_outpstream_st out; R_pstream_format_t type = R_pstream_binary_format ; SEXP (*hook)(SEXP, SEXP) = NULL ; con = getConnection(Rf_asInteger(connection)); R_InitConnOutPStream(&out, con, type, 0, hook, R_NilValue ); return R_NilValue ; } The problem I have is that I cannot actually call getConnection since it is not part of the api. Is there another way to get the Rconnection that is associated with a number. Many thanks. Romain -- Romain Francois Professiona...
