DataInfo

<code>DataInfo</code>: exhibits basic data information

Provides simple functions to compute and plot two types
(sample-size- and coverage-based) rarefaction and extrapolation curves for species
diversity (Hill numbers) based on individual-based abundance data or sampling-unit-
based incidence data; see Chao and others (2014, Ecological Monographs) for pertinent
theory and methodologies, and Hsieh, Ma and Chao (2016, Methods in Ecology and Evolution)
for an introduction of the R package.

Interpolation and Extrapolation for Species Diversity

DataInfo function

<dl><dt>x</dt>
<dd>a vector/matrix/data.frame/list of species abundances or incidence frequencies. If <code>datatype = "incidence_freq"</code>, 
then the first entry of the input data must be total number of sampling units, followed by species incidence frequencies.</dd>
<dt>datatype</dt>
<dd>data type of input data: individual-based abundance data (<code>datatype = "abundance"</code>),
sampling-unit-based incidence frequencies data (<code>datatype = "incidence_freq"</code>) or species by sampling-units incidence matrix (<code>datatype = "incidence_raw"</code>).</dd></dl>
