I addition to Phil`s comment: -clear*- would kill all your -scalar-s anyway.


Just use a -local-, then:


*******
sysuse auto, clear
loc number = _N

clear*
set obs  `number'
egen byte myseq = fill(1 2 3 1 2 3)
*******

BTW, I am having a hard time imagining why you need to -clear- in between
and start anew. What`s the context?

Now I got stuck again when trying to merge my sequence variable to the
original dataset

"original dataset"
count
scalar number = r(N)


clear*
set obs  number
egen float myseq = fill(1 2 3 1 2 3)


Am I not allowed to use the scalar number together with -set obs-

Welcome to the club:

BTW, your original -expand- idea is probably more cumbersome than the
alternatives shown:

****
clear*
set obs 3
gen byte seq=_n
gen byte cl=1
expandcl 10, cluster(cl) generate(newcl)
sort newcl seq
drop cl newcl
l
****

Oh, thanks again. I tried -fill- but I didn´t understand how to make it
repeat itself.

-egen, fill()- would have taken you there as well:


*******
clear*
set obs 99
egen float myseq = fill(1 2 3 1 2 3)
l
*******

Subject: st: Sequence of numbers

Dear Listers,

Is it possible to generate a variable with a sequence of numbers that
repeats itself, for example 1, 2, 3, 1, 2, 3, 1, 2, 3.

I tried -egen fill- but that didn´t work. Another solution would be to make
a new dataset with tree lines with the values 1, 2, 3 and use -expand- and
finally merge that together with the first dataset. However it would be nice
if someone had a simple solution of how to do it within the dataset.

/Tomas
