Species vector (see sppVector).

genVector

Genus vector that defines the genera of each individual, created in a similar manner to the species vector.

thresh

Threshold for adequate individual/species number. Default of 5.

data(anoteropsis)
#Species vector
anoSpp <- sapply(strsplit(dimnames(anoteropsis)[[1]], split="_"), 
    function(x) paste(x[1], x[2], sep="_"))
#Genus vector
anoGen <-  sapply(strsplit(anoSpp, split="_"), function(x) x[1])
dataStat(anoSpp, anoGen)
