R help - Nov 2001 - tracking data

hello,
is it possible in R to combine with a RODBC query 
a timing/date function to refresh plots and analysis after 
a time step automatic ( example: i get via php/mySql every day 100 records and
would like refresh a linear regression every end of day at 8.00 p.m. ) ?

thanks for advance
& Regards,christian

Yes, in particular with the tcltk toolkit and its event loop.  I can't name
the command with which you would control the event loop, though.

If you want to keep it in R itself, just use something like 

   while(1) {
     do_my_data_gathering_from_mySQL()
     do_my_plotting()
     Sys.sleep(24*60*60)	# sleep one day
   }

with suitable code in those two do_my_* functions.
