Here's a hint: > args(panel.qqmath) function (x, f.value = NULL, distribution = qnorm, qtype = 7, groups = NULL, ...) panel.qqmath() does not have a 'y' argument, which should tell you that qqmath() does not pass a 'y' argument to its panel function. -Deepayan ______________________________________________ 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.
