If you have a quantile function for any distribution, you can make a QQ plot using ppoints() and the quantile function. The Rayleigh distribution isn't in base R, but Google says it is in the VGAM, lmomco, reliaR, etc. packages. Pick one of those, e.g. VGAM, which calls the quantile function "qrayleigh". Then if you have a sample x and want to compare to Rayleigh with scale 1, you do library(VGAM) qqplot(qrayleigh(ppoints(length(x))), x) Duncan Murdoch ______________________________________________ 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.
