   r.li.richness calculates the "richness's diversity index" as:
   [rliRichness_formula.png]
   with:
     * m: number of different patch type

ÐÐ ÐÐÐÐ Ð«

   To calculate richness's diversity index on map my_map, using my_conf
   configuration file and saving results in my_out file run:

r.li.richness map=my_map conf=my_conf output=my_out

ÐÐ ÐÐÐÐ§ÐÐÐÐ¯

   Do not use absolute path names for output files. They are raster if
   moving window disposition was selected, otherwise they are in
   ~/.r.li/output folder.
   If input raster is full of null values r.li.richness returns -1.
   If you want to have null values instead run
   after index calculation.
