## Box-Whisker Plot Methods in Package ‘flexclust’

### Description

Seperate boxplot of variables in each cluster in comparison with boxplot for complete sample.

### Usage

    ## S4 method for signature 'kcca'
    bwplot(x, data, xlab="",
           strip.labels=NULL, strip.prefix="Cluster ",
           col=NULL, shade=!is.null(shadefun), shadefun=NULL, byvar=FALSE, ...)
    ## S4 method for signature 'bclust'
    bwplot(x, k=x@k, xlab="", strip.labels=NULL,
           strip.prefix="Cluster ", clusters=1:k, ...)

### Arguments

`x` | An object of class `"kcca"` or `"bclust"`.
`data` | If not `NULL`, cluster membership is predicted for the new data and used for the plots. By default the values from the training data are used.
`xlab, ...` | Graphical parameters.
`col` | Vector of colors for the clusters.
`strip.labels` | Vector of strings for the strips of the Trellis display.
`strip.prefix` | Prefix string for the strips of the Trellis display.
`shade` | If `TRUE`, only boxes with larger deviation from the median or quartiles of the total population of the respective variables are filled with color.
`shadefun` | A function or name of a function to compute which boxes are shaded, e.g. `"medianInside"` (default) or `"boxOverlap"`.
`byvar` | If `TRUE`, a panel is plotted for each variable. By default a panel is plotted for each group.
`k` | Number of clusters.
`clusters` | Integer vector of clusters to plot.

### Examples

      set.seed(1)
      cl <- cclust(iris[,-5], k=3, save.data=TRUE)
      bwplot(cl)
      bwplot(cl, byvar=TRUE)

      ## fill only boxes with color which do not contain the overall median
      ## (grey dot of background box)
      bwplot(cl, shade=TRUE)

      ## fill only boxes with color which do not overlap with the box of the
      ## complete sample (grey background box)
      bwplot(cl, shadefun="boxOverlap")
