Bootstrap estimates of the decomposed Shannon's diversity index with fragments

Description

Computes bootstrap confidence intervals of the decomposed Shannon's diversity index using evidence from fragments

Usage

bs_frag(x, gx, f, gf, B = 1000, cl = 0.95)

Arguments

x	Vector of dimension S (number of species) with the number of individuals observed in each species. NA values are allowed.
gx	Vector of dimension S of factors indicating the group of each species. G groups.
f	Vector of dimension G with the number (>0) of fragments in each group
gf	Vector of dimension G of factors indicating the groups to which the fragments "f" belong.
B	Number of bootstrap samples. The default is 1000.
cl	Confidence level. A value between 0 and 1. The default is 0.95.

Value

• ci_sh: Confidence interval for Shannon's diversity index with fragments.

• ci_bt: Confidence interval for "between groups".

• ci_wt: Confidence interval for "within groups".
