index.bio {agricolae} | R Documentation |
Scientists use a formula called the biodiversity index to describe the amount of species diversity in a given area.
index.bio(data, method = c("Margalef", "Simpson.Dom", "Simpson.Div", "Berger.Parker", "McIntosh", "Shannon"), level=95, nboot=500, console=TRUE)
