## Derivative of the Normal Distribution's Density Function

### Description

This function returns the derivative(s) of the density function of the normal (Gaussian) distribution with respect to the quantile, evaluated at the quantile(s), mean(s), and standard deviation(s) specified by arguments `x`, `mean`, and `sd`, respectively.

### Usage

    ddnorm( x, mean = 0, sd = 1 )

### Arguments

`x` | quantile or vector of quantiles.
`mean` | mean or vector of means.
`sd` | standard deviation or vector of standard deviations.

### Value

numeric value(s): derivative(s) of the density function of the normal distribution with respect to the quantile
