## Stacked histogram

### Description

Stacked histogram

### Usage

    histStack(x, breaks, breaksFun=paste, ylab="frequency", ...)

### Arguments

`x` | A list of numeric vectors.
`breaks` | Histogram breaks, as in `hist`
`breaksFun` | Function, can be used to control the formatting of the bin labels. See example.
`ylab` | Label for the Y-axis on the plot
`...` | Further arguments that get passed to `barplot`

### Details

The function calls `hist` for each element of `x` and plots the frequencies as a stacked barplot using `barplot` with `beside=FALSE`.

### Value

The function is called for its side effect, producing a barplot on the active graphics device. It returns the result of the call to `barplot`.

### Examples

      x    <- list(rnorm(42), rnorm(42)+2)
      br   <- seq(-3, 5, length=13)
      cols <- c("#1D267B", "#ceffc0")
      histStack(x, breaks=br, col=cols)

      histStack(x, breaks=br, col=cols,
                breaksFun=function(z) paste(signif(z, 3)))
