I have been using -ds- to identify r(varlist) and then loop through those
variables. However, I am puzzled by the behavior of -ds, has(type #/#)-
syntax.
To illustrate what appears to be inconsistent behavior of -ds-, consider
this dataset with 9 string variables:
. desc
Contains data from uniondemoc82-3.dta
obs: 180
vars: 10
size: 40,500 (99.9% of memory free)
-------------------------------------------------------------------------------
storage display value
variable name type format label variable label
-------------------------------------------------------------------------------
union str80 %80s
id int %8.0g
pres1 str20 %20s
treas1 str17 %17s
sect1 str20 %20s
sect2 str16 %16s
st1 str20 %20s
st2 str16 %16s
st3 str11 %11s
vp1 str19 %19s
. ds
union id pres1 treas1 sect1 sect2 st1 st2 st3
vp1
. ds , has(type string)
union pres1 treas1 sect1 sect2 st1 st2 st3 vp1
. ds, has(type 2/8)
. ds , has(type 2/62)
pres1 treas1 sect1 sect2 st1 st2 st3 vp1
. ds , has(type 2/11)
st3
My goal is to have r(varlist) contain all the variables except the first
two (union and id), one of which is a string, other other numeric.
The question here is why -ds- lists some of the variables, specific
variables, or all variables.
