Betreff: st: drop multiple observations

Hi listers,

If I have a dataset with 1000 observations (uniquely identified using
variable - id -), can I drop multiple observations using one line? I know
one can drop observations that are say id>350 or <20, but if the
observations are all over the place could we still use a one line command?

For example, instead of typing:

drop if id==2
drop if id==215
drop if id==302
drop if id==420
drop if id==579

Can I use one line to drop all the above?

Thank you,
