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?
> s <- aggregate(income,list(age,sex),function(x) (svymean(~x,design=d.na)))
Error in aggregate(income, list(age, sex), function(x) (svymean(~x, :
Object "income" not found
