If you don't get this message it suggests that you do have a built-in dataset called China, which will have overwritten your file. > dchina<-svydesign(id=~psu,strata=~strata,weights=~weight0x, data=China,nest=TRUE) If this line doesn't produce an error message then a variable called "dchina" must have been produced, in which case you shouldn't get an error message saying it wasn't found in the next line. > summary(dchina) > Are you sure there wasn't an earlier error message from the call to svydesign()? -thomas ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
