Plot a dendrogram

Source: R/distance_dendro.R

Plot a dendrogram of a matrix of (distance) scores.

distanceDendro(distance_scores, cluster_method = "average")

Arguments

distance_scores

A Matrix::Matrix() containing (distance) scores between 0 and 1.

cluster_method

character, indicating the clustering method for the stats::hclust() function. See the stats::hclust() function for the available options. Defaults to 'average'.

Value

A ggdendro::ggdendrogram() plot object.

Examples


## Mock example showing how the data should look like

distance_scores <- Matrix::Matrix(0.5, 20, 20)
distance_scores[c(11:15), c(2:6)] <- 0.2
dendro <- distanceDendro(distance_scores, cluster_method = "single")

## Example using the data available in the package
data(scores_macrophage_topGO_example_small,
     package = "GeDi",
     envir = environment())
dendro <- distanceDendro(scores_macrophage_topGO_example_small,
                        cluster_method = "average")
