plotDendro {celda} | R Documentation

## Plots dendrogram of 'findMarkers' output

### Description

Generates a dendrogram of the rules and performance (optional) of the decision tree generates by 'findMarkers'.

### Usage

    plotDendro(
      decisionTree,
      classLabel = NULL,
      addSensPrec = FALSE,
      maxFeaturePrint = 4,
      leafSize = 24,
      boxSize = 7,
      boxColor = "black"
    )

### Arguments

`decisionTree` | List object. The output of 'celda::findMarkers'.
`classLabel` | A character value. The name of a label to which draw the path and rules. If NULL (default), the rules for every cluster is shown.
`addSensPrec` | Logical. Print training sensitivities and precisions for each cluster below leaf label? Default is FALSE.
`maxFeaturePrint` | A numeric value. Maximum number of feature IDs to print at a given node. Default is 4.
`leafSize` | A numeric value. Size of text below each leaf. Default is 24.
`boxSize` | A numeric value. Size of rule labels. Default is 7.
`boxColor` | A character value. Color of rule labels. Default is 'black'.

### Value

A ggplot2 object

### Examples

    library(M3DExampleData)
    counts <- M3DExampleData::Mmus_example_list$data
    # Subset 500 genes for fast clustering
    counts <- as.matrix(counts[1501:2000, ])
    # Cluster genes ans samples each into 10 modules
    cm <- celda_CG(counts = counts, L = 10, K = 5, verbose = FALSE)
    # Get features matrix and cluster assignments
    factorized <- factorizeMatrix(counts, cm)
    features <- factorized$proportions$cell
    class <- clusters(cm)$z
    # Generate Decision Tree
    decTree <- findMarkers(features,
        class,
        oneoffMetric = "modified F1",
        threshold = 1,
        consecutiveOneoff = FALSE)

    # Plot dendrogram
    plotDendro(decTree)
