Similarly to what can be read on help(qqplot), however using Rayleigh distribution:
library(VGAM) p <- ppoints(100) x <- qrayleigh(p) y <- rrayleigh(100) qqplot(x,y) qqline(y, distribution = function(p) qrayleigh(p), prob = c(0.1, 0.6), col = 2) -- GG [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
