R help - Oct 2009 - convenience question

On: R 2.8.1 / Ms Windows / R-Gui-R-console

I have a long-ish function, and to re-assure myself that it's 
actually making progress I've arranged a set of messages to the 
console (using cat). But what happens is that the messages don't 
actually display until the function  has finished, which sort of 
negates the purpose. However, if I hit Return after starting the 
function, then all is well. I'm pretty sure that what's happening is 
that the function isn't yielding time to the operating system in 
order that messages be processed: so my question is, is there any way 
to do that within the function? Or maybe, to simulate the Return keystroke?

Thanks!

Add a flush.console() statement after each cat.
