Repeating and parallelizing a function in R with the purrr and furrr packages (CC192)

March 3, 2022 • PD Schloss • 1 min read

In this episode Pat writes a function in R that needs to be repeated for different input values. He shows how to do this with purrr’s map_dfr and then speeds things up by parallelizing it with furrr’s future_map_dfr. The specific question in this episode is how the sampling depth of communities impacts pairwise Bray-Curtis distances calculated using avgdist from vegan. He’ll show how to synthesize and visualize the data using tools from dplyr, ggplot2, and other tidyverse packages.
