.SH DESCRIPTION
\fIr.li.patchnum\fR is a patch index for r.li program.
.br
It calculates the function 
.br
\fI f(sample_area)= Patch_Number \fR
.br
This index is calculated using a 4 neighbour algorithm
.br
.SH EXAMPLES
To calculate patch number index on map my_map, using 
\fImy_conf\fR configuration file and saving results in
my_out file run:
\fC
.DS
.br
r.li.patchnumber map=my_map conf=my_conf out=my_out
.br
.DE
\fR
.SH NOTES
An that is full of null values is considered to have zero patch. 
.br
If you want to have null values instead run 
.br
\fC
.DS
.br
r.null setnull=0 map=my_map
.br
.DE
\fR
after index calculation.
