Correlation heatmap

Description

Correlation heatmap

Usage

plotCorrelationHeatmap(object, ...)

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

Arguments

object	Object.
normalized	character(1) or logical(1). Normalization method to apply: FALSE: Raw counts. When using a tximport-compatible caller, these are length scaled by default (see countsFromAbundance argument). When using a featureCounts-compatible caller, these are integer. tximport caller-specific normalizations: "tpm": Transcripts per million. Additional gene-level-specific normalizations: TRUE / "sf": Size factor (i.e. library size) normalized counts. See DESeq2::sizeFactors for details. "fpkm": Fragments per kilobase per million mapped fragments. Requires fast = FALSE in bcbioRNASeq() call and gene annotations in rowRanges() with defined width(). See DESeq2::fpkm() for details. "vst": Variance-stabilizing transformation (log2). Requires fast = FALSE to be set during bcbioRNASeq() call. See DESeq2::varianceStabilizingTransformation() for more information. "tmm": Trimmed mean of M-values. Calculated on the fly. See edgeR::calcNormFactors() for details. "rle": Relative log expression transformation. Calculated on the fly. See relativeLogExpression() for details. "rlog": Deprecated. Regularized log transformation (log2). No longer calculated automatically during bcbioRNASeq() call, but may be defined in legacy objects. See DESeq2::rlog() for details. Note that VST is more performant and now recommended by default instead. Note that logical(1) support only applies to counts(). Other functions in the package require character(1) and use match.arg() internally.
...	Passthrough to SummarizedExperiment method defined in AcidPlots. See AcidPlots::plotCorrelationHeatmap() for details.
