Defining a POV (undefined, as is `schmuck') as `not something' is really 
non-communication.  Please do read the R posting guide and its references, 
and try to formulate questions in standard (and polite) English.  Also, 
check the correct list to use as described in that posting guide -- R-help 
is not intended for questions involving programming concepts (like 
`syslog', which needs explanation even there).

It's not clear what you mean by this.  If you mean send warnings and 
messages to stdout (what is `STDOUT'?) then `why?'  You deal with this the 
same way as any other Linux application that uses stderr for warning/error 
messages.

To `tee' output, see ?sink, or indeed `man tee'.

R is principally an interactive program used for exploration.  You haven't 
told us what you are trying to do, and you may be better off embedding R 
in some other front end to give you more control.
