st: running marginsplots without rerunning margins again

[Doug Hess <douglasrhess@gmail.com>]

Thanks to Richard and Scott. Scott's suggestion worked
perfectly...once I figured out that "foo" wasn't a command
abbreviation.

I'm not familiar with starting a command with the underscore (as in -
_retrun hold foo  - ), what is that underscore doing?

Likewise, I'm not familar with the colon after a command line (as in -
estimates esample: - ), what does that colon do there?

Thanks again.

-Doug

It looks like you to save the contents of r() as well.

clear*
webuse nhanes2
regress bpsystol agegrp##sex
estimates save foo,replace
margins agegrp
_return hold foo

//other stuff
sysuse auto ,clear
regress price i.rep
margins rep

//return to marginsplot
webuse nhanes2,clear
est use foo
estimates esample:
_return restore foo
marginsplot
