For eg i have following dfs

a <- mtcars
b <- aggregate(cyl ~ mpg , data = a , sum)

I want to monitor how much progress this aggregate function has made while it performs . Any idea ?

    Be warned that adding progress bars can substantially increase calculation time, which if it is already long enough to warrant a progress bar is going to be very undesirable. – JeremyS Mar 17 '16 at 06:06
  • @akrun : Thanks for the hint . . but i want to add it into a function as shown above, not in a loop . I was just wondering if there is any way this could be done for a standalone function itself. – Pankaj Kaundal Mar 17 '16 at 06:15
  • Maybe you can take a look a the new waiter package: https://github.com/JohnCoene/waiter – Alessio Mar 31 '19 at 01:09
