Webdcauchy, pcauchy, and qcauchy are respectively the density, distribution function and quantile function of the Cauchy distribution. rcauchy generates random deviates from the Cauchy. The length of the result is determined by n for rcauchy, and is the maximum of the lengths of the numerical arguments for the other functions. Webx: numeric vector of observations. Missing (NA), undefined (NaN), and infinite (Inf, -Inf) values are allowed but will be removed.censored: numeric or logical vector indicating which values of x are censored. This must be the same length as x.If the mode of censored is "logical", TRUE values correspond to elements of x that are censored, and FALSE …
