Converts the aravo data of the ade4 package (Choler 2005) into the
long format used by tidydiversity: 82 alpine plant species in 75 sites
in the Aravo valley (French Alps), with 6 site variables (including
snowmelt date, Snow, and physical disturbance, PhysD) and 8
functional traits. The data are loaded from ade4, not copied into
tidydiversity.
Value
A list with community (a tibble with site, species,
cover (abundance class 0-5) and the site variables) and traits (a
tibble with species and the 8 traits).
