plotDistances {clst} | R Documentation

## Visualize results of `link{findThreshold}`

### Description

The functions `plotDistances` and `plotMutinfo` are used to visualize the distance threshold calculated by `findThreshold` in the context of pairwise distances among objects in the reference set.

### Usage

    plotDistances(distances, D = NA, interval = NA,
                  ylab = "distances", ...)

    plotMutinfo(breaks, D = NA, interval = NA,
                xlab = "distance", ylab = "mutual information", ...)

### Arguments

`distances` | The `$distances` element of the output value of `findThreshold`
`breaks` | The `$breaks` element of the output value of `findThreshold`
`D` | The distance threshold
`interval` | The range of values over which candidiate values of PMMI are evaluated.
`xlab` | Label the x axis of the plot.
`ylab` | Label the y axis of the plot.
`...` | Additional arguments are passed to `bwplot` (`plotDistances`) or `xyplot`

(`plotMutinfo`)

### Details

`plotDistances` produces a box-and-whisker plot contrasting within- and between-group distances. `plotMutinfo` produces a plot of cutpoints vs mutual information scores.

### Value

Returns a lattice grid object.

    dmat <- as.matrix(dist(iris[,1:4], method="euclidean"))
    groups <- iris$Species
    thresh <- findThreshold(dmat, groups)
    do.call(plotDistances, thresh)
    do.call(plotMutinfo, thresh)
