plotBarcodeHistogram — plotBarcodeHistogram • bartools

Generate proportional stacked bar plot of barcodes from raw count object with n most frequent barcodes labelled.

Usage

plotBarcodeHistogram(
  dgeObject,
  topN = 10,
  seedColors = 1,
  samples = NULL,
  orderSamples = NULL,
  alphaLowFreq = 1
)

dgeObject: DGEList object with barcode counts.
topN: Number of most frequent barcodes to show in legend (integer). Default = `10`.
seedColors: Seed for sampling colors (integer). Default = `1`.
samples: Samples to plot (vector of strings). Default all.
orderSamples: One or multiple samples to order barcodes by (string or vector of strings). Default all.
alphaLowFreq: Alpha of barcodes not in top n barcodes (decimal). Default = `1`.

Returns a stacked bar plot of barcode frequencies within samples
