This vignette demonstrates how to compute Pielou’s evenness index for nominal variables using the pielou_evenness function from the nomiShape package. Pielou’s evenness quantifies how evenly individuals are distributed across categories in a nominal variable.

Computing Pielou’s Evenness

# Example usage of pielou_evenness

#> [1] 0.9981314

# Example usage of pielou_evenness
pielou_evenness(categories2, "animal")
#> [1] 0.9462875

# Example usage of pielou_evenness
pielou_evenness(categories3, "animal")
#> [1] 0.6553931
