Tabulate frequencies, with zeros explicit

  tabcount7 varname [if exp] [in range] , values(value list)

by ... : may be used with tabcount7; see help by.

  

Description

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

tabcount7 was called tabcount. Stata 8 users are recommended to use the much
more general tabcount from SSC.


Options

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


Examples

    . tabcount7 rep78, v(1/5)

    . bysort foreign: tabcount7 rep78, v(1/5)
