Dactylopterus volitans sound comparison code

R code for comparison of the three sound types (Grunt A, Grunt B and Juvenile). The code utilizes the Excel table provided in this repository. First, it initializes the Kruskal-Walis test (with Wilcoxon pairwise test), and then it subsamples the sounds to the number of juvenile sounds (n = 10), bootstraps and compares the initial and permutated results.
