Storing results in Stata

[mtaimoor23]

How can I store result of a command in a separate variable.For example after giving command "corrgram ",how to save AC at lag 1 in a new variable.I request any Stata user to kindly answer to this question.

[Joseph Coveney]

Doesn't ac , generate() work for you? See the help file for corrgram and take a look at the options for the companion command, ac.

Dear Joseph I did'nt understand what you are trying to say.I am talking about any result to store in a separate variable.coorgram was just an example

[Nick Cox]

Your question is about "any command". Some commands explicitly put results in new variables.

For other commands, see http://www.stata.com/manuals13/u.pdf 18.8 and/or help return. In most cases, putting new results in a macro or scalar or matrix is a better idea than using a new variable.

As a new user, please study http://www.statalist.org/forums/help especially Sections 3, 4 and 6.

Dear Nick Cox,Thank you for your suggestions.After reading Stata Manual I was unable to find answer to my question.Will you please elaborate by giving an example?

mtaimoor23,
1) after any command you can explore the saved results in r(), e(), s(). The particular type depends on the type of command: r-class, e-class, s-class. A mix is also possible.
2) not all commands make available everything they compute internally and/or show to the user; consult documentation for a particular command.
3) saved results are not available as a single object (if this is what you mean by your question). For estimation commands you can save the results with 'estimates store'.
Hope this helps, Sergiy Radyakin

i have gone through ereturn list command but this is not what I want.I want to save to autocorrelation at lag 1 (AC1) computed from corrgram command so that I can use this result for future analysis.

[Nick Cox]

Your question has already been answered more than once in various ways. Joseph pointed you to help corrgram which explains that the first autocorrelation is available in r(ac1).
