R: Visualize results of 'link{findThreshold}'

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.

Examples

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