## Plot a Histogram with Automatic Bin Width Selection

### Description

Plot a histogram with automatic bin width selection, using the Scott or Freedman-Diaconis formulae.

### Usage

    hist.scott(x, prob = TRUE, ...)
    hist.FD(x, prob = TRUE,  ...)
    nclass.scott(x)
    nclass.FD(x)

### Arguments

`x` | A data vector
`prob` | Should the plot have unit area, so be a density estimate?
`...` | Further arguments to `hist`.

### Details

`nclass.scott` uses Scott's choice for a normal distribution based on the estimate of the standard error, and `nclass.FD` uses the Freedman-Diaconis choice based on the inter-quartile range.

### Value

For the `nclass.*` functions, the suggested number of classes.

### Side Effects
