%description
Find, visualize and explore patterns of differential taxa in vegetation
data (namely in a phytosociological table), using the Differential Value
(DiffVal). Patterns are searched through mathematical optimization
algorithms. Ultimately, Total Differential Value (TDV) optimization aims
at obtaining classifications of vegetation data based on differential
taxa, as in the traditional geobotanical approach.  The Gurobi optimizer,
as well as the R package 'gurobi', can be installed from
<https://www.gurobi.com/products/gurobi-optimizer/>.  The useful vignette
Gurobi Installation Guide, from package 'prioritizr', can be found here:
<https://prioritizr.net/articles/gurobi_installation_guide.html>.
