[R] debug print() commands not showing during file write loop

[Richard Evans]

Hello,

I have a for loop that takes about and hour to complete each loop. I
added a "print()" command at the end of the looped code as a way to see
its progress, but the output is suppressed until the entire for-loop is
finished. why is that? can it be changed such that the print() output is
echoed to the screen when it is processed?

thanks in advance,
