Gehard, if do you want to know the quantiles of the new distribution created by "myfunction". Maybe you can also do: x <- seq(0,1,.01) # insert your 'x' q <- myfunction(x) # And: quantile(x) 0% 25% 50% 75% 100% 0.000000 1.476177 2.045389 2.581226 2.817425 # This gives the sample quantiles. You can also look foward to simulations (like Bert Gunter had suggested) to know better the properties of distributions quantiles obtained after 'myfunction'. ----- Victor Delgado cedeplar.ufmg.br P.H.D. student www.fjp.mg.gov.br reseacher -- View this message in context: http://r.789695.n4.nabble.com/calculate-quantiles-of-a-custom-function-tp4256887p4257551.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
