However, Stata provides the implementation shortcut marksample to implement this restriction. Then, the if-restriction must be applied: we can preserve the data and then drop the ineligible observations before running more code.
This is an appropriate choice here for several reasons: preserve will always restore the data to the original state at the end of program execution, no matter what happens later in the program, due to its scope; restore is not even needed here. For this reason, we will often only use preserve in this context in programming, and prefer other methods for loading and re-loading data inside the program block.
Other syntax elements work similarly, although they are not parsed through marksample except in. See the helpfile for details. Finally, the options syntax allows optional triggers to be implemented. Let's allow the user to request value labels, by writing:. Otherwise it will be empty. Therefore simple conditionals allow options to be checked and executed. Now we could run:. However, we can see that the command would then fail if we ran levelslist region state , val , because state is a string variable and cannot have labels.
So we might want to allow the user to specify a list of variables to show labels for, as the following:. Because we now allow the option as [VALuelabels string asis ] , it will either contain the string written into the option or it will contain nothing.
We need to rewrite the implementation slightly. Second, we need to use a tool like strpos to check if a variable occurs in the list - when we write the helpfile, we will make clear that this option needs to take a list of variables.
Is is possible to require this through the options syntax itself but it can introduce issues if, for example, the command first loads data, a varlist check might fail on the data currently in memory. In this kind of operation, it is doubly clear that the full names of variables need to be used to avoid needing to pull in commands like unab.
Also, note the use of extra spacing around both arguments of strpos ; these ensures that variables whose name are a substring of another do not trigger the option.
