Description Usage Arguments Value Examples
Evenness
: compute six evenness indices of order q.
1 |
data |
a data.frame, matrix or list of observed species-by-assemblage frequency vector. For the case of only one assemblage (site), dat should be a numeric vector of species frequency. |
q |
a vector of diversity orders: user must specify a vector (default is from 0 to 2 in an increment of 0.1) |
nboot |
an integer specifying the number of bootstrap times to build confidence interval. Use 0 to skip bootstrap. |
conf |
a number between 0 and 1 specifying the confidence level. Default is 0.95. |
a list of N dataframes, where N is the number of assemblages (sites). Each data.frame shows the profiles of all six classes of evenness indices listed in Chao and Ricotta (2019) Ecology paper.
