Dear Statalisters,

Using Stata 11 MP 64bit (Win Server 2008R2) I am confused about some functionality of -table-.

I use the following code:

.	oneway `var' fachuhdfak, means scheffe
.	table fachuhdfak if r(F)>= .25, c(m `var' sd `var' med `var')

.	ttest `var', by(muhd)
.	table muhd if r(p) <= .05, c(m `var' sd `var' med `var')

The first -table- command line reports also missing values of variable fachuhdfak - although missing as an option is not specified. Do I misinterpret the missing option?
Table looks like:
X1
X2
X3
.n
.z

The second -table- command line produces the error no observatios (r(2000)) as r(p) is higher than .05. I wonder why -tab2- is ignoring that there are no observations but -table- produces an error?

Any ideas/hints/clarifications?
