DESCRIPTION

r.report allows the user to set up a series of report parameters to be applied to a raster
map layer, and creates a report. If invoked with command line arguments, the report will
print out to the screen only. However, output may be redirected to a file or another
program using the UNIX redirection mechanism. If invoked without command line arguments,
the user is given the option of printing out each report and/or saving output to a file.

The report itself consists of two parts, a header section and the main body of the report.

The header section of the report identifies the raster map layer(s) (by map layer name and
TITLE), location, mapset, report date, and the region of interest. The area of interest is
described in two parts: the user's current geographic region is presented, and the mask is
presented (if any is used).

The main body of the report consists of from one to three tables which present the
statistics for each category and the totals for each unit column.

Note that, unlike r.stats, r.report allows the user to select the specific units of
measure in which statistics will be reported.

Following is the result of a r.report run on the raster map layer geology (located in the
Spearfish, SD sample data base), with the units expressed in square miles and acres. Here,
r.report output is directed into the file report.file.

EXAMPLE:

       r.report map=geology units=miles,acres > report.file

NOTES

       If  the  user runs r.report interactively and saves the report output in a file, this file
       will be placed into the user's current working directory.

       If the user runs r.report non-interactively, report output can be saved by redirecting  it
       to a file or a printer using the UNIX redirection mechanism.

       To output computer-friendly data suitable for importing into a spreadsheet use the r.stats
       module. In fact r.report is running r.stats in the background and reformatting the results
       to be more human-friendly.
