Plot a Heatmap of Peak Annotation Hypergeometric Enrichment in Marker Peaks.

This function will plot a heatmap of hypergeometric enrichment of a given peakAnnotation within the defined marker peaks.

plotEnrichHeatmap(
  seEnrich = NULL,
  pal = paletteContinuous(set = "comet", n = 100),
  n = 10,
  cutOff = 20,
  pMax = Inf,
  clusterCols = TRUE,
  binaryClusterRows = TRUE,
  labelRows = TRUE,
  rastr = TRUE,
  transpose = FALSE,
  returnMatrix = FALSE,
  logFile = createLogFile("plotEnrichHeatmap")
)

Arguments

seEnrich

A SummarizedExperiment object containing peak enrichment information returned by peakAnnoEnrichment().

pal

A custom continuous palette (see paletteContinuous()) used to override the default continuous palette for the heatmap.

n

The number of top enriched peakAnnotations per column from the seMarker to display in the heatmap. This number can be lowered to improve visibility of the heatmap.

cutOff

A numeric cutOff that indicates the minimum P-adj enrichment to be included in the heatmap.

pMax

A numeric representing the maximum P-adj for plotting in the heatmap.

clusterCols

A boolean indicating whether or not to cluster columns in the heatmap.

binaryClusterRows

A boolean indicating whether or not to cluster rows using binary classification in the heatmap.

labelRows

A boolean indicating whether or not to label all rows in the heatmap.

rastr

A boolean value that indicates whether the plot should be rasterized using ComplexHeatmap. This does not rasterize lines and labels, just the internal portions of the plot.

transpose

A boolean determining whether to transpose the heatmap in the plot.

returnMatrix

A boolean determining whether to return the matrix corresponding to the heatmap rather than generate a plot.

logFile

The path to a file to be used for logging ArchR output.
