Usage

index.bio(data, method = c("Margalef", "Simpson.Dom", "Simpson.Div", 
"Berger.Parker", "McIntosh", "Shannon"),level = 95, nboot = 500, noprint=FALSE)

Arguments

number of specimens

method

Describe method bio-diversity

level

Significant level

size bootstrap

noprint

Value

• data
  vector
• method

• level
  value 0-100 percentage
• nboot
