vector of quantiles (values of the variable).
vector of probabilities.
number of observations. If length(n) > 1, the length is taken to be the number required.
length(n)
location parameter (default 0); potentially a vector.

scale parameter (default 1); potentially a vector.

logical; if TRUE (the default) probabilities and quantiles correspond to \(P(X \le x)\), if FALSE to \(P(X > x)\).
