[R] using aggregate with survey-design and survey functions

[Spencer Graves]

In the following command: 

    s <- aggregate(income,list(age,sex),function(x) 
(svymean(~x,design=d.na)))

Since 'is.element("income", objects())' was FALSE, it was not in the 
search path, which it must be for "aggregate" to find it.  I suggest you 
read or reread something like "An Introduction to R", downloadable from 
"www.r-project.org" -> "Manuals". 

hope this helps.
