NOTE: This is a Test-version and is not sufficiently checked for correctness so far. Simultaneous confidence intervals for differences and ratios of Simpsons indices of diversity are calculated from data sets with repeated samples of communities and designs with more than two treatments groups. The intervals are calculated based on a stratified, non-parametric ordinary bootstrap sample of Simpsonindices, and applying the Algorithm of Besag et al.(1995) on the joint empirical distribution of differences (BOOTSimpsonD) or ratios (BOOTSimpsonR) of the original distribution.

X |
a data.frame of dimension n times p, containing integer entries as species counts of p species from n independent samplings |
f |
a factor, usually with more than two levels. Must be of length n, when X is an n times p matrix |
type |
a single character string, defining a contrast type. Supported options are 'Dunnett','Tukey','Sequen'; for more options, see |

alternative |
a single character string, one of 'two.sided','less' and 'greater' |
