27   Parameters:
28       map=name
29           Name of input raster map
30
31       conf=string
32           Configuration file
33
34       output=name
35           Name for output raster map
36

DESCRIPTION

38       r.li.richness calculates the "richness's diversity index" as:
39       with:
40
41                     m: number of different patch type
42
43

EXAMPLES

45       To calculate richness's diversity index on map  my_map,  using  my_conf
46       configuration file and saving results in my_out file run:
47
48       r.li.richness map=my_map conf=my_conf output=my_out

NOTES

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