where :

      {it:stat} is the statistic variable - not optional - (to be calculated by {cmd:tabstat}),

      {it:bygroup} is a list of the by-{it:variables} (more than 2 could be specified), 
      separated by spaces, 

      {it:clean} is the character to be removed specified by the user,

      {it:format} is the format type,

      {it:name} is the name of the save matrice of results (default is M),

      {it:output} is the option to export results,

      {it:trim} is the length to assign to value labels,

      {it:short} applies the trimming size to all labels.


{title:Description}

{p 4 4 2}{cmd:tablemat} is an extension of {help tabstat}.

{p 4 4 2}{cmd:tablemat} produces a matrice of results using {cmd:tabstat}. 

{p 4 4 2}The statistics available are those of {cmd:tabstat} except q.
The weights options are also those supported by {cmd:tabstat}. The improvement over 
{cmd:tabstat} is that {cmd:tabstat} allows only one  -by- variable while {cmd:tablemat} allows
as many by-variables as the user wishes.  Another advantage is the handle of labels. 


{p 4 4 2}Version 8.2 or higher is required.

{title:Aknowledgements}

{p 4 4 2}Some parts of this program have been built through my incessant questions to Stata List.
I would like to thank Nick Cox, Kit Baum and other stata users for their patience and their helpful comments
on various aspects of this program. Kit Baum earlier found a bug that has been fixed.
