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)
