## Table of Fuzzy Biological Traits

### Description

This data set coleo (coleoptera) is a a fuzzy biological traits table.

### Usage

    data(coleo)

### Format

`coleo` is a list of 5 components.

tab

  is a data frame with 110 rows (species) and 32 columns (categories).

species.names

  is a vector of species names.

moda.names

  is a vector of fuzzy variables names.

families

  is a factor species family.

col.blocks

  is a vector containing the number of categories of each trait.

### Examples

    data(coleo)
    op <- par(no.readonly = TRUE)
    coleo.fuzzy <- prep.fuzzy.var(coleo$tab, coleo$col.blocks)
    fca1 <- dudi.fca(coleo.fuzzy, sca = FALSE, nf = 3)
    indica <- factor(rep(names(coleo$col), coleo$col))

    if(adegraphicsLoaded()) {
      glist <- list()
      for(i in levels(indica)) {
        df <- coleo$tab[, which(indica == i)]
        names(df) <- coleo$moda.names[which(indica == i)]
        glist[i] <- s.distri(fca1$l1, df, psub.text = as.character(i), ellipseSize = 0,
          starSize = 0.5, plot = FALSE, storeData = TRUE)
      }
      G <- ADEgS(glist, layout = c(3, 3))

    } else {
      par(mfrow = c(3, 3))
      for(j in levels(indica))
        s.distri(fca1$l1, coleo$tab[, which(indica == j)], clab = 1.5, sub = as.character(j),
          cell = 0, csta = 0.5, csub = 3, label = coleo$moda.names[which(indica == j)])
      par(op)
