Using the purrr and broom R packages to easily perform thousands of statistical tests (CC112)

Functions from the purr and broom R packages are a powerful combination if you need to iterate or repeat a function over multiple groups of data. In this episode of Code Club, Pat uses the nest, map, tidy, and unnest functions to run kruskal.test and pairwise.wilcox.test to test for evidence of significant differences across thousands of taxa in a microbiome data analysis. Pat will use RStudio and the #map, #tidy, and #nest functions from the purrr and broom packages. The accompanying blog post can be found at https://www.riffomonas.org/code_club/....
