As part of clarifying and tightening the R API for packages the non-API entry points ATTRIB and SET_ATTRIB will be removed from installed header files and, where possible, hidden from package access. Both expose internal structure that might need to be changed and also make it too easy to inadvertently break consistency assumptions about the values of some attributes. Using these functions is will now result in check NOTEs. These check NOTEs will soon be replaced by WARNINGs; this will probably happen by the end of January. The 'Working with attributes' section in the 'Writing R Extensions' list some alternatives. Additional functions for working with attributes, without exposing internal attributes structure, could be added if they are needed.
