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.

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.
