{title:Tabulate frequencies, with zeros explicit}

{cmd:tabcount7}
{it:varname} 
[{cmd:if} {it:exp}] 
[{cmd:in} {it:range}] 
{cmd:,}
{cmdab:v:alues(}{it:value list}{cmd:)}

{p}{cmd:by ... :} may be used with {cmd:tabcount7}; see {cmd:help by}.  

  

{title:Description}

{p}{cmd:tabcount7} tabulates frequencies. Its one distinctive feature 
is that zero frequencies -- of one or more specified values -- are    
shown explicitly. 

{p}{cmd:tabcount7} was called {cmd:tabcount}. Stata 8 users 
are recommended to use the much more general {cmd:tabcount} from 
SSC. 


{title:Options}

{p 0 4}{cmd:values(}{it:value list}{cmd:)} specifies a list of values 
whose frequencies (zero or more) are to be shown. Numeric values
may be (strictly, must be) shown as a {help numlist}. String values 
containing spaces or double quotes should be in double quotes
or compound double quotes. This is a required option. 


{title:Examples}

{p 4 8}{inp:. tabcount7 rep78, v(1/5)}

{p 4 8}{inp:. bysort foreign: tabcount7 rep78, v(1/5)}
