bubble_clust {deepMOU}

Bubble plot

Description

Bi-dimensional representation (via Multi-Dimensional Scaling) of the clusters, where each bubble corresponds to a cluster, its size is proportional to the relative frequency of documents and color saturation reflects cluster cohesion.

Usage

bubble_clust(
  x,
  clusters,
  bubble_size = 1,
  bubble_col = c("red", "white"),
  cex_text = 1,
  main = NULL
)

Arguments

x

Document-term matrix describing the frequency of terms that occur in a collection of documents. Rows correspond to documents in the collection and columns correspond to terms.

clusters

Integer vector of length of the number of cases, which indicates a clustering. The clusters have to be numbered from 1 to the number of clusters.

bubble_size

Graphical parameter for bubbles size.

bubble_col

Choose palette with two colors (default "red" and "white"). The first (darker) color will denote homogeneous clusters, while the latter (lighter) more heterogeneous ones.

cex_text

Size of texts inside bubbles.

main

A title for the plot.

Value

A graphical aid to visualize and to describe the obtained clusters.

Examples

# Load the CNAE2 dataset
data("CNAE2")

# Perform parameter estimation and clustering
mou_CNAE2 = mou_EM(x = CNAE2, k = 2)

# Usage of the function
bubble_clust(mou_CNAE2$x,mou_CNAE2$clusters, bubble_size = 5 )
