a vector/matrix/list 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").
Value
a data.frame of basic data information including sample size, observed species richness, sample coverage estimate, and the first ten abundance/incidence frequency counts.
