Diversity: Estimating a continuous diversity profile in one community including species rich-
ness, Shannon diversity and Simpson diversity). This function also supplies plots of empirical and
estimated continuous diversity profiles. Various estimates for Shannon entropy and the Gini-
Simpson index are also computed. All five types of data are supported: Type (1) abundance data
(datatype="abundance"), Type (1A) abundance-frequency counts
(datatype="abundance_freq_count"), Type (2) incidence-frequency data (datatype =
"incidence_freq"), Type (2A) incidence-frequency counts (datatype="incidence_freq_count"), and
Type (2B) incidence-raw data (datatype="incidence_raw"); see
SpadeR-package details for data input formats.

$Basic_data for summarizing data information.
$Species_richness for showing various species richness estimates along with related statistics.
$Shannon_diversity for showing various Shannon index/diversity estimates.
$Simpson_diversity for showing two Simpson index/diversity estimates.
$Hill_numbers for showing Hill number (diversity) estimates of diversity orders specified in the argument
