[R] the survey package
Good afternoon! I'm trying to use the survey package to get a better point of view for my data, but i need some piece of advice: i have some data from a survey which has been stratified using 2 criteria: region(7 values), size of locality(5 values) Using the survey pakage how can i define in a correct way this design (taking into account all 4 strata not just one as in the Survey example) i have tried design<- svydesign(ids=~0, strata= c(~regiune,~size_loc), data=tabel) # for 2 criteria and got this error Error in strata[, 1] : incorrect number of dimensions My "tabel" looks like this: cod cantitate pondere regiune size_loc size_hhage_hhh 7405977.604 0.9962673 1 1 3 52 74213879.362 0.8674601 1 1 3 42 743 7876.3220.9845403 1 1 4 53 7451169.084 1.1690844 11 3 50 7464430.431 0.9845403 11 350 751 3938.161 0.9845403 1 1 2 39 What does it mean and where was i wrong? I'm sorry for taking up your time but i don't know how to fix my problem. Thank you! - Luggage? GPS? Comic books?
