[R] determining a parent function name

[Sundar Dorai-Raj]

Hi, Vladimir,

Sorry, didn't see this reply. .Traceback <- NULL doesn't work because of 
the warning in ?traceback.

Warning:

      It is undocumented where '.Traceback' is stored nor that it is
      visible, and this is subject to change.  Prior to R 2.4.0 it was
      stored in the workspace, but no longer.

Thanks,

--sundar
