Thanks to those who helped me with my question yesterday. One more quick question after that.
I'm trying to extract a scalar value from a vector and use it in a forval loop. The code I have is this:
foreach s in 6 8 17 21 {
keep if state == `s'
forval i = XXX (1) 16 {
....
}
}
It's the XXX that is the problem. I have a vector x that takes on different values for each state s, and I want the forval loop to run from that value to 16. In other words, x == 14 when s == 6, x == 10 when s == 8, and so on. But I have a lot of observations per state, so while x is constant for each state it is still a vector. How do I extract its scalar value to insert where the big XXX is in my code? This seems like it should be simple, but I've been thwarted for a while now.
Thanks so much!
All the best,
John Pfaff
