   r.li.mpa (mean pixel attribute) calculates the average value of the
   attribute of all the non-null cells in the sampling area as:
   [rlimpa_formula.png]
   with:
     * i: attribute
     * m: number of non-null attributes in the sampling area
     * wi: number of cells of attribute i
     * size: size of sampling area (in cells)

ÐÐ ÐÐÐРЫ

   To calculate mean pixel attribute index on map my_map, using my_conf
   configuration file and saving results in my_out file run:

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

ÐÐ ÐÐÐЧÐÐÐЯ

   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.mpa consider to have 0
   patch.
   If area is 0 r.li.mpa returns -1; it is possible only if the raster is
   masked
   If you want to have null values instead run

r.null setnull=-1 map=my_map

   after index calculation.
