[R] Print to console from within Sweave script

[Werner W.]

Hi,

is it possible to send some message to the console from within a .Rnw Sweave 
script, ie. when executing Sweave()?
The background is that only in particular circumstances my script is doing some 
lengthy computations and I would like to print some status information to the 
console. It seems Sweave redirects all output though.

Any suggestions?

Thanks a lot for considering my question.

All the best
  Werner
