R help - Mar 2013 - Controlling print messages/warnings and error output in R package

Hello,

If i were to embed R (in C), i could over ride

ptr_R_ShowMessage = Re_ShowMessage;
ptr_R_WriteConsoleEx =Re_WriteConsoleEx;

where Re_ShowMessage,Re_WriteConsoleEx are my own functions.

How would i do this in a package?
I would like the flexibility of having my function be called /every-time/
the programmer calls print/cat/message/warning or stop.

Are there hooks i can write code for?
Regards
Saptarshi
