A quick question related to dropping variables: I would like to drop a  
variable when a certain condition is met (I'm using loops to check  
whether a variable is not empty for each year of observation). AFAIK, - 
drop- and -keep- only refer to observations if being used  
conditionally, e.g. I cannot use "drop THISVAR if mean_THISVAR<1".

So, how can I drop a variable when a certain condition is met?
