## 1-D Density Plot (Histogram) of Clustering Results

### Description

This method generates a one-dimensional density plot for the specified dimension (variable) based on the robust model-based clustering results. A histogram of the actual data or cluster assignment is optional for display.

### Usage

    ## S3 method for class 'flowClust'
    hist(x, data = NULL, subset = 1,
      include = 1:(x@K), histogram = TRUE, labels = TRUE,
      ylab = "Density", main = NULL, col = NULL, pch = 20, cex = 0.6,
      ...)

    ## S3 method for class 'flowClustList'
    hist(x, ...)

### Arguments

`x` | Object returned from `flowClust` or from running `filter` on a `flowFrame` object.
`data` | A numeric vector, matrix, data frame of observations, or object of class `flowFrame`. This is the object on which `flowClust` or `filter` was performed.
`subset` | An integer indicating which variable is selected for the plot. Alternatively, a character string containing the name of the variable is allowed if `x@varNames` is not `NULL`.
`include` | A numeric vector specifying which clusters are shown on the plot. By default, all clusters are included.
`histogram` | A logical value indicating whether a histogram of the actual data is made in addition to the density plot or not.
`labels` | A logical value indicating whether information about cluster assignment is shown or not.
`ylab` | Labels for the x- and y-axes respectively.
`main` | Title of the plot.
`col` | Colors of the plotting characters displaying the cluster assignment (if `labels` is `TRUE`). If `NULL` (default), it will be determined automatically.
`pch` | Plotting character used to show the cluster assignment.
`cex` | Size of the plotting character showing the cluster assignment.
`...` | other arguments xlim The range of x-values for the plot. If `NULL`, the data range will be used. ylim The range of y-values for the plot. If `NULL`, an optimal range will be determined automatically. breaks Content to be passed to the `breaks` argument of the generic `hist` function, if `histogram` is `TRUE`. Default is 50, meaning that 50 vertical bars with equal binwidths will be drawn. ... Further arguments passed to `curve` (and also `hist` if `histogram` is `TRUE`).
