st: RE: Re: Writing values to a file

[Nick Cox <n.j.cox@durham.ac.uk>]

I just wouldn't use -file write- for this purpose. Consider some variant on 

keep if ld <= 0.001 
gen long order = _n
bysort repeat (order) : keep if _n == 1 
outsheet group repeat l ls e using whatiwant.txt 

The first line might be ... ld > 0.001: I can't work out which way round you are selecting.

I would be grateful for some advice on writing a value to a file. I have a dataset where I need select a particular value, the first value exceeding a threshold value,and the process is repeated over 240 groups. I can list the values but I am unable to write the values to a file for subsequent use. My code - and I know it is awful programming - is:

capture : file close myfile
file open myfile using "elong.txt", write replace
	file write myfile ("repeat,e") _n
capture : drop marker
gen marker=0
forvalues i=1/24{
replace marker=1 if repeat==`i' & ld > 0.001
su id1 if marker==0 & repeat==`i'
list group repeat l ls e if repeat==`i' & id1==r(min)
	file write myfile (e) if repeat==`i' & id1==r(min)
	file write myfile ","
	file write myfile (`i') _n
}
file close myfile
