Hello all,
I am using Rprintf in a C for loop (from .Call) to print a progress indicator
showing the current percent complete. The loop I am doing is an time intensive
call to another function. I have noticed that Rprintf does not print to the
R-window until the entire loop has been completed. When it reaches the end of
the loop it suddenly prints 0 percent to 100 percent in a split second. For
less intensive function calls it prints properly while looping. My question is
this: is there any way to force Rprintf to print to the screen during a loop?
On a related note, how can I show a percent sign in the output? For example,
Rprintf("0%"); only prints a zero.
Thanks!,
Erik
