Have you considered that the reason it doesn't work is because you don't
have any observations with a value exactly at the mean? Instead try running
almost the exact same code with a few changes:
clear
set obs 10
ge id = _n
ge var1 = uniform()
qui: su var1
local LCmin =`r(min)'
local LCmean =`r(mean)'
local LCmax =`r(max)'
di `LCmean'
list
count if var1==`LCmin'
count if var1==`LCmean'
count if var1==`LCmax'
HTH,
Billy

Subject: st: problem with `r(min)' and `r(mean)' macros
Dear statalist,
I am summarising a variable and then trying to use the `r(.)' macros
However, in some instances Stata does not seem to find any variables that
take the `r(min)' and `r(mean)' values. For some reason, it does work with
`r(max)' instead.
The code below should clarify the problem. When I run it, I always get that
no observation takes the min or the mean (why???), but there is an
observation that takes the max.
The problem does not depend on whether I use the original `r(min)' or a
macro=`r(min)'.
If it matters I am using a mac osx 10.8 with Stata 12.1 MP.
Any hint would be appreciated because it is driving me crazy.
Mario
