st: RE: RE: Macro display format

Sorry if this is a silly question.

I did the following sequence of commands. I closed the scatter as soon as it opened. No other commands.

Why does r(mean) go away after you use it in the scatter with the formatting extended function?

. sysuse auto, clear (1978 Automobile Data)

. quietly summ length

. di `r(mean)' 187.93243

. di `: di %9.1f `r(mean)'' 187.9

. di `: di %9.1f `r(mean)'' 187.9

. twoway scatter length mpg, text(200 35 "The mean of length is:`: di %2.1f `r(mean)''")

. di `: di %9.1f `r(mean)''

. di `r(mean)'

No. You should try

` : di %9.1f `r(mean)''

See help extended_fcn.

Tip: I would go `: di %2.1f `r(mean)'' even if you are sure that format is too restrictive. You're likely to be wrong, as Stata will stretch the space to avoid damage. However, with %9.1f you are likely to get the ugly spaces that are a consequence of what you asked for.
