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)
par(mfrow = c(3,3))
indica <- factor(rep(names(coleo$col), coleo$col))
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)
par(mfrow = c(1,1))
