Hi R-help, I posted about this late yesterday but got no response. I may have put TMI in the original request. Not to mention I couldn't cut and paste yesterday because I was working R off a non-network computer while asking for help on a network computer.
Essentially, I have this user-defined function: test <- function(X){ chisq <- svychisq(~X + SEX, design=audit, statisic="adjWald", round=4) } test(con) "con" is a data variable in my design object audit. When I just run: chisq <- svychisq(~X + SEX, design=audit, statisic="adjWald", round=4) It works just fine. It's only when it's nested in the function test() that it falls apart. I get this error: Error in `[.data.frame`(design$variables, , as.character(rows)) : undefined columns selected How can I solve this problem? Thanks, Jen (obviously a new R-user, as of late 2009) ______________________________________________ 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.
