If you prefer to do your iterative tasks using the`purrr` family of functional programming tools, rather than with`for` loops, there are two straightforward ways to add progress bars:

If you prefer to do your iterative tasks using the`purrr` family of functional programming tools, rather than with`for` loops, there are two straightforward ways to add progress bars:

1. Increment the ticks*in-line* when calling the`purrr` iterator.

2. Define the task and increment the ticks in a separate wrapper function.

2. Define the task and increment the ticks in a separate wrapper function.

***Option 1*** is concise for simple one-line tasks (*e.g.* requiring only a single function call), while***Option 2*** is probably preferred for more complex multi-line tasks.

The package also provides a C++ API, that can be used with or

without Rcpp. See[the example package](https://github.com/r-lib/progress/blob/HEAD/tests/testthat/progresstest/src/test.cpp) that

is[included](https://github.com/r-lib/progress/blob/HEAD/tests/testthat/progresstest) within`progress`. Here is a short excerpt
