Can we use Recode to classify values as missing values
1)I want to classify negative values as missing values. Can we use Recode to accomplish this. If yes, how can we do it? I can create a new formula column while using Recode. I see it as a two step process. I was wondering if this could be accomplished in a single step.2) If we use data filters, can recode be used in the subset of the filtered data with out affecting the rest.
