Hello Statalisters,
I am having an issue with using the stored `r(min)' value from a sum command. I am looking at test results for schools and I want to keep all schools that have test data less than or equal to the minimum value of the conditions that I have set. When I run the code, it is not keeping the school that has the minimum value found in the sum command. What am I doing wrong?

Here is a sample of my data
Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input long schl float(keep percent_on_gl2015Math)
7846 .     0
3849 . .0363
6492 . .0388
3847 . .0467
7855 . .0533
8148 1 .0588
8308 . .0588
8303 . .0625
7852 . .0714
5286 . .0714
6172 . .0714
7506 . .0769
7922 . .0816
5275 . .0909
7245 . .0921
3857 . .0956
7293 . .1026
3851 . .1038
6675 .  .104
7255 . .1041
end

Here is a simplified example of the issue I am running into.
When I run the following sum command to get the minimum test value for all school that have a 1 in the keep variable, i get:
Code:
sum percent_on_gl2015Math if keep ==1

    Variable |        Obs        Mean    Std. Dev.       Min        Max
-------------+---------------------------------------------------------
percen~5Math |         14    .3142571    .1791266      .0588      .6587
I then run the following to try to keep all values that are less than or equal to .0588 (the minimum value in the above sum output)
Code:
. keep if percent_on_gl2015Math <= `r(min)'

It does not keep the 2 observations that are equal to the minimum value:

Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input long schl float(keep percent_on_gl2015Math)
7846 .     0
3849 . .0363
6492 . .0388
3847 . .0467
7855 . .0533
end
Thank you all for your help!

I am using IC 15.1 for Windows 64 bit
