## S4 method for signature 'bcbioRNASeq'
plotCorrelationHeatmap(object, normalized = c("rlog",
  "vst", "tmm", "tpm"), ...)

Arguments

object

Object.

normalized

Character indicating which normalization method to apply:

  • "tpm": Transcripts per million (tximport).

  • "tmm": edgeR trimmed mean of M-values. Calculated on the fly.

  • "rlog": DESeq2 log2 regularized log transformation.

  • "vst": DESeq2 log2 variance stabilizing transformation.

...

Passthrough arguments to SummarizedExperiment method.

Value

Show heatmap and invisibly return a list of the components.
