a vector of species abundances or incidence frequencies. If datatype = "incidence",
then the first entry of the input data must be total number of sampling units, followed by species incidence frequencies.
datatype
data type of input data: individual-based abundance data (datatype = "abundance") or sampling-unit-based incidence data (datatype = "incidence").
transform
a logical constant to compute traditional Shannon entropy index (transform=FALSE) or the transformed Shannon diversity (transform=TRUE).
conf
a positive number $\le$ 1 specifying the level of confidence interval.
B
an integer specifying the number of bootstrap replications.
Value
A vector of observed Shannon entropy/diversity, estimate of entropy/diversity, s.e. and the associated confidence interval.
