I have a different comment. I can't see what you want to
achieve by creating a variable with integers running from
1 to _N. To see this: I just did the -gen- and -codebook- for a dataset
I have in memory, but all the information can be constructed
without knowing anything but _N. It says nothing about the
particular data.
. codebook id
--------------------------------------------------------------------------------
id (unlabeled)
--------------------------------------------------------------------------------
type: numeric (float)
range: [1,40] units: 1
unique values: 40 missing .: 0/40
mean: 20.5
std. dev: 11.6905
percentiles: 10% 25% 50% 75% 90%
4.5 10.5 20.5 30.5 36.5
I may be missing something here, but if you want to know how many observations
you have, you can (e.g.)
. count
or even look at the file without reading it in.
So you can go something like
local country "Benin Togo France"
foreach i of local country {
qui d using `i'
di "`i'" _col(20) `r(N)'
}
Or perhaps this was just a toy example, and nothing to do with
the real problem.
