In nfultz/stackoverflow: Stack Overflow's Greatest Hits

Description

Density, distribution function, quantile function and random generation from a kernel density estimate (using linear approximation).

Usage

ddensity(x, d)

pdensity(q, d)

qdensity(p, d)

rdensity(n, d)

Arguments

x	a vector
d	a density object
q	a vector
p	a vector of probabilities
n	number of observations. If length(n) > 1, the length is taken to be the number of required
