It was designed to mimic the head function in R. For variables with value labels, the {opt l:abel} option can be used to list value labels rather than values. To only display unique values, specify {opt u:nique} (e.g. if the first three values are 9, 9, 10 and {cmd:n(2)} and {opt u:nique} are specified, the values displayed will be 9, 10 instead of 9, 9). Specifying {opt s:orted} will display the head observations of the data set after sorting it by {varlist}. To not display the variable name header, specify {opt noh:eader}; the default is to display the variable names unless {varlist} only contains one variable (to display the header if {varlist} contains one variable, specify {opt h:eader}). {title:Examples} {phang} {cmd:. sysuse auto}{p_end} {phang} {cmd:. head price}{p_end} {phang} {cmd:. head price, n(2) header}{p_end} {phang} {cmd:. head price make, unique}{p_end} {phang} {cmd:. head price foreign, unique sorted label}{p_end} {phang} {cmd:. head price foreign, unique sorted noheader}{p_end} {title:Author} {p 4 4 2}Sean Higgins, Tulane University, shiggins@tulane.edu
