Calculate the Bray-Curtis dissimilarity index (or Sorensen-Dice similarity index) between two sites (with site compositions given as vectors).

Usage

bray_curtis(site1, site2, sorensen_dice = FALSE)

Arguments

site1	An atomic vector containing a set of observations (the observations at the first site).
site2	An atomic vector containing a set of observations (the observations at the second site).
sorensen_dice	If TRUE, the Sørensen-Dice similarity index (one minus Bray-Curtis dissimilarity index) is returned (FALSE by default)

Details

No dependencies.

Value

A number [0, 1].

Examples

area1 <- c('bubble-tip anemone', 'bubble-tip anemone', 'beaded sea anemone',
           'sebae anemone', 'magnificent sea anemone')
area2 <- c('bubble-tip anemone', 'bubble-tip anemone', 'bubble-tip anemone',
           'corkscrew tentacle sea anemone')
bray_curtis(area1, area2)
