[R-br] table with >= 2^31 elements

[Roney Fraga Souza]

Pessoal, 

Utilizando o pacote survey resolvi estratificar a amostra de uma base de dados de com as seguintes dimensões:

> dim(mydata)
[1] 20274412        4

com o seguinte comando:

monom00.svy <- svydesign(id=~V0300, strata=~AREAP, weights=~P001p, data=mydata) 

obtive a seguinte mensagem de erro:
Error in table(ids[, 1], strata[, 1]) : 
  attempt to make a table with >= 2^31 elements

Com o comando traceback() tenho:
6: stop("attempt to make a table with >= 2^31 elements")
5: table(ids[, 1], strata[, 1])
4: is.data.frame(x)
3: rowSums(table(ids[, 1], strata[, 1]) > 0)
2: svydesign.default(id = ~V0300, strata = ~AREAP, weights = ~P001p, 
       data = mydata)
1: svydesign(id = ~V0300, strata = ~AREAP, weights = ~P001p, data = mydata)

Alguém tem alguma sugestão de como lidar com isso?
