The dol.count data set is a data frame with 297 observations on the following 4 variables.

samp: a factor with levels for samples.
taxa: a factor with levels for the species.
count: a numeric vector with count data.
segm: a factor with levels for segments.

The dol.samp data set is a data frame with 24 observations on the following 2 variables.

microhab: a factor with levels dead.wood litter live.wood rock for microhabitats.
method: a factor with levels time quadrat for the sampling method applied.

The dol.taxa data set is a data frame with 121 observations on the following 4 variables.

species: a factor with levels the species names.
author: a factor with levels for authors of the species and description dates (accents are removed).
familia: a factor with levels for family level classification.
size: a numeric vector for major shell dimension of the adult specimen.

The data sets are results of the 'DOLINA 2007' expedition (Vilisics et al. 2008). Species characteristics are based on Kerney et al. (1983). The full dataset (S\'olymos & Kemencei 2008) from which this example was derived is available at the Dataverse Network (hdl:1902.1/12060) with the code to make the subsetting.
