keep if

[Silvana Builes]

Hi,
I want to use " keep if" to keep a subset of observations in my dataset, but I get an error: Type mismatch

This is the instruction I'm giving: keep if P1_DEPARTAMENTO==11

What am I doing wrong?

I would guess that P1_DEPARTMENTO is not actually a numeric variable. It's data type is different from what your code leads Stata to expect, hence the error. Perhaps it is a string variable?

Hermanshu! Yes, you're right! I just realized that and doing this: P1_DEPARTAMENTO=="11", worked!

thank you
