st: combine foreach and if

[Vincent Koppelmans <vkoppel@umich.edu>]

I want to loop over a couple of time points in a dataset and filer out certain rows.
I tried to combine a foreach loop with an if statement, but it is not working (it only prints the results using the first value of the numlist):


foreach TIME of numlist 1 5 {
if time == `TIME' {
summ DS_sec_
plot DS_sec_ Subject_ID
}
}


The following code however is working:

foreach TIME of numlist 1 5 {
summ DS_sec_ if time == `TIME'
plot DS_sec_ Subject_ID if time == `TIME'
}

In this simple example the syntax does not differ a lot in length, but the actual code that needs to be executed is much longer. I therefore would prefer a solution that resembles my initial code, because that would mean that I do not have to add the "if time == `TIME'" part after each line.

How can I do this?

Thanks,

- Vincent
