R: PAC Landscape Plot

pac_landscape {ClustAssess} | R Documentation

## PAC Landscape Plot

### Description

Plot final PAC values across range of k to find optimal number of clusters.

### Usage

    pac_landscape(pac_res, n_shade = max(pac_res$iteration)/5)

### Arguments

`pac_res` | The data.frame output by consensus_cluster.
`n_shade` | The PAC values across the last n_shade iterations will be shaded to illustrate the how stable the PAC score is.

### Value

A ggplot2 object with the final PAC vs k plot. A local minimum in the landscape indicates an especially stable value of k.

### Examples

    pac.res = consensus_cluster(iris[,1:4], k_max=20)
    pac_landscape(pac.res)
