plotCorrelationHeatmap: Plot Correlation Heatmap

In WeiSong-bio/roryk-bcbioRNASeq: RNA-Seq Utilities

Description

This function calculates a correlation matrix based on feature expression per sample.

Usage

## 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.
