Fauna Table with double (row and column) partitioning
This data set gives information about species of benthic macroinvertebrates in different sites and dates.
data(ardeche)
ardeche is a list with 6 components.
is a data frame containing fauna table with 43 species (rows) and 35 samples (columns).
is a vector containing the repartition of samples for the 6 dates : july 1982, august 1982, november 1982, february 1983, april 1983 and july 1983.
is a vector containing the repartition of species in the 4 groups defining the species order.
is a date factor for samples (6 dates).
is a site factor for samples (6 sites).
is a species order factor (Ephemeroptera, Plecoptera, Coleoptera, Trichoptera).
The columns of the data frame ardeche$tab define the samples by a number between 1 and 6 (the date)
and a letter between A and F (the site).
