[R] printing a variable during a loop

[Antonio Olinto]

Thanks Adrienne, but I still in doubt. The behavior of print and  
message looks the same.

Nothing is displayed on the screen after minutes of routine processing  
. All values of "i" are displayed only when I press the stop button  
(I'm under Windows) or when "i" reaches the maximum value.

Thanks again,

Antônio Olitno
