Azov {FuzzyQ}

Helminth communities of so-iuy mullets from the Sea of Azov

Description

Abundance of 25 helminth species from 378 so-iuy mullets collected in the Sea of Azov and the Black Sea. Fish are grouped in 12 surveys.

Usage

data(Azov)

Format

A data frame with 378 rows and 26 columns. The first column (sample) is a survey identifier. The remaining columns correspond to species abundances. See source for species abbreviations and survey identifiers.

Examples

data(Azov)
# Apply the FuzzyQ algorithm to each survey:
fuzzyq.azov <- by(Azov[, -1], Azov[, "sample"], fuzzyq, rm.absent = FALSE)
# Get cluster membership, silhouette widths and commonness indices
# per sp. per survey:
sppsilw.azov <- lapply(fuzzyq.azov, function(x) x$spp)
# Get global silhouette withds, commonness indices and Dunn's normalized
# partition coefficient per survey:
global.azov <- t(sapply(fuzzyq.azov, function(x) x$global))
