Webfurrr Overview. The goal of furrr is to combine purrr’s family of mapping functions with future’s parallel processing capabilities. The result is near drop in replacements for purrr functions such as map() and map2_dbl(), which can be replaced with their furrr equivalents of future_map() and future_map2_dbl() to map in parallel.. The code draws heavily from …
