= Stata Stored Results =

Stata commands internally compute intermediary and final values. These can be useful for programming, so they are exposed as '''stored results'''.

<<TableOfContents>>

----



== R Class ==

The `r()` class stores results from general syntax commands. As an example:

{{{
count if EXPR
local total=r(N)
}}}

Try `return list, all` to see all stored results available in the `r()` class. Leaving off the `all` option hides some results.

----


== E Class ==

The `e()` class stores results from estimations.

Try `ereturn list, all` to see all stored results available in the `e()` class. Leaving off the `all` option hides some results.

----



== S Class ==

The `s()` class stores results from parsing commands.

Try `sreturn list` to see all stored results available in the `s()` class.

----



== N Class ==

The `n()` class stores results that don't belong in any of the `r()`, `e()`, or `s()` classes.

----



== C Class ==

Not actually a class for stored results: see [[Stata/SystemParameters|System Parameters]].
