Hi
I have a large dataset in stata and one of the variables has a lot a observations that should be missing values but are instead zero length strings (ie. =="")
I've tried
foreach x of varlist myvariable {
replace `x' = . if(`x' =="")
}
but this gives a type mismatch.
Can anyone help please?
Thanks
Rob Shaw
