MoE_Similarity function

Plot the Similarity Matrix of a MoEClust Mixture Model

Produces a heatmap of the similarity matrix constructed from the res$z matrix at convergence of a MoEClust mixture model.

MoE_Similarity(res,
               col = grDevices::heat.colors(30L, rev=TRUE), 
               reorder = TRUE, 
               legend = TRUE,
               ...)

Arguments

• res: An object of class "MoEClust" generated by MoE_clust, or an object of class "MoECompare" generated by MoE_compare. Models with a noise component are facilitated here too.
• col: A vector of colours as per image. Will be checked for validity.
• reorder: A logical (defaults to TRUE) indicating whether observations should be reordered for visual clarity.
• legend: A logical (defaults to TRUE) indicating whether to append a colour key legend.
• ...: Catches unused arguments, or arguments to be passed to hclust when reorder=TRUE.

Returns

The similarity matrix in the form of a heatmap is plotted; the matrix itself can also be returned invisibly. The invisibly returned matrix will also be reordered if reordered=TRUE.

Note

plot.MoEClust is a wrapper to MoE_Similarity which accepts the default arguments, and also produces other types of plots.

Examples

data(ais)
mod <- MoE_clust(ais[,3:7], G=2, modelNames="EEE", gating= ~ SSF + Ht,
                 expert= ~ sex, network.data=ais, tau0=0.1, noise.gate=FALSE)
sim <- MoE_Similarity(mod)
