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?
