Drop all variables except

[Ashvinder Singh]

Dear Statalist community,

I have a large panel dataset that I am attempting to do a summary statistics on. I am only using several variables (and its respective observations) and would like to drop the rest. I could drop these other variables one by one, but that would be too many.

Is there a command on Stata that I can input to say "Drop all variables except x y z" ?

Thank you.

You may prefer to use - keep - for that, assuming you wish to, well, keep fewer variables than the ones you want to drop.

Example:

keep x y z
