Hi, I would like to use the quantile function, but I have some doubts to choose the value of "type" parameter. Does this depend on the shape/structure of my distribution? I cannot unde rstand what mean the expressions Discontinuous sample quantile and Continuous sample quantile, respectively. My distributions (histograms) sometimes have some "holes", that is I have some bins with zero samples. Someone can help me, please? thank you! giov -- View this message in context: http://www.nabble.com/help-on-quantile-tp19921087p19921087.html Sent from the R help mailing list archive at Nabble.com.
