Hi R users,
I am trying to use the aggregate function with a survey design object and survey functions, but get the following error. I think I am incorrectly using the syntax somehow, and it may not be possible to access variables directly by name in a survey-design object. Am I right? How do I fix this problem? I have used aggregate with "mean" and "weighted.mean", and that works fine. I am trying to find out where the difference is. What would be an efficient alternative to aggregate for a large dataset?
