Hi R users. I have a problem with function strata in sampling packages.
> st0 = strata(dom, stratanames="stratas", size=sample.size, method="systematic",pik, FALSE) Error in sort.list(y) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? In previous version of R 2.9.1 and previous version of package sampling this code worked well and now I don't know what is a problem? Any ideas how to solve this problem will be very useful? Thanks in advance Andrija [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
