Plot a heatmap — distanceHeatmap • GeDi

Plot a heatmap of a matrix of (distance) scores of the input genesets

distanceHeatmap(distance_scores, chars_limit = 50)

Arguments

distance_scores: A Matrix::Matrix() of (distance) scores for each pairwise combination of genesets.
chars_limit: Numeric value, Indicates how many characters of the row and column names of distance_scores should be plotted. Defaults to 50 and prevents crowded axes due to long names.

Value

A ComplexHeatmap::Heatmap() 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
rownames(distance_scores) <- colnames(distance_scores) <- as.character(c(1:20))
p <- distanceHeatmap(distance_scores)

## Example using the data available in the package
data(scores_macrophage_topGO_example_small,
     package = "GeDi",
     envir = environment())
p <- distanceHeatmap(scores_macrophage_topGO_example_small)
