R: Plotting Distance Graphs

circleplot.dist {cba} | R Documentation

## Plotting Distance Graphs

### Description

Function for visualizing distance graphs using a circular layout.

### Usage

    circleplot.dist(x, cutoff = 0.5, col = 1, circle = FALSE,
                    scale = 1.4)

### Arguments

`x` | an object of class `dist`.
`cutoff` | a numeric value specifying the threshold for edge exclusion.
`col` | a number or string specifying the edge color to use.
`circle` | a logical value specifying if a circle connecting the nodes should be drawn.
`scale` | a numeric value specifying the plot range (the default accommodates node labels).

### Details

Plots the distance graph of `x` placing its nodes on a circle such that the number of crossing edges is approximately minimized. This is achieved by using `order.dist` for seriation.

### Examples

    ##
    data(iris)
    d <- dist(iris[,-5])[[1:26]]
    circleplot.dist(d, col = 2, scale = 1)

    dimnames(d) <- LETTERS[1:26]
    circleplot.dist(d)
