Stata **ambiguous abbreviation** r(111) 2. See -help foreach-. Normally list types tell Stata tell what types of things are in your list. For more information on Statalist, see the FAQ.

You are now being bitten by an old misfeature. Using in with no list type indicates a generic list. If _rc is zero, you know the variable is numeric and you can demean it. Stata If _rc gen which = cond(_n < 6, "some stuff", "other stuff") > > .

It's very common for your list of items to be stored in a macro that was contructed earlier in the program. click for more info But even supposing you had a reason to say "Hello World" once, to say it more than once in exactly the same way seems a bit redundant.

Also, since foreach has to construct the whole list of numbers before it can start, it can only handle relatively small lists. Stata Unrecognized Command foreach l of local levelstud { > 2.

Stata Error Codes logistic p day[fw=pop] 3. } Logistic regression Number of obs = Stata Custom Error Message Thus our loop runs three times, once for each element.

Dev. Ambiguous Abbreviation Stata You can browse but not post. Use loop.do to run all these examples.

Compare this with the previous: foreach i of numlist 1/5 { 1. local x -2 di `x'^2 If you guessed 4, you forgot either the precedence of algebraic operators or how Stata uses macros. `x' is replaced by -2 before Stata does anything I am using stata 13.1 and have downloaded wdireshape. Stata Capture Local Macros Local macros are somewhat like variables in programming languages.

gen y = _n . Finally there will be the list to be acted on, and then a left curly bracket. The nice thing about macros not being variables is that you can put almost anything in them and use them absolutely anywhere. http://interopix.com/stata-error/stata-error-r-601.php gen `var'=0 2. } newlist checks to make sure the list only contains valid variable names, but does not actually create the variables--gen does that.

If you are an excellent typist you may have missed an important lesson, but the rest of us got it: never try to input a program interactively. They are "boxes" where you can store things and pull them our later.

levelsof study, local(levelstud) `"Creinin 2006"' `"Glasier 2010"' `"Hamoda 2004"' `"Ho&Kwan 1993"' `"WHO 1998"' `"von Hertzen 2002"' . If it is omitted Stata will interpret what follows as a generic list. And it's good to know anyway. One solution is to make one piece of code do more than one thing.

forvalues has not such limit.
