plotCorAcrossRef {InTAD} | R Documentation

## Function to plot correlation across genome

### Description

This function creates a plot of correlation strength in target genomic region from the result table. The X-coordinates represent signals, Y-coords represent genes, while each dot represents -log10(P-value) from correlation test. Additionallly all TAD boundaries can be visualized.

### Usage

    plotCorAcrossRef(obj, corRes, targetRegion, showCorVals = FALSE,
      symmetric = FALSE, tads = NULL)

### Arguments

`obj` | InTADSig object with signals and genes combined in TADS
`corRes` | Correlation result table created by function findCorrelation()
`targetRegion` | Target genomic region visualise.
`showCorVals` | Use this option to visualize postive correlation values instead of correlation strength
`symmetric` | Activate mirrow symmetry for gene-signal connections
`tads` | TAD regions to visualize. By default only TADs persent in correlation result table are applied (NULL value).

### Value

A `ggplot` object for visualization or customization.

### Examples

    inTadSig <- newSigInTAD(enhSel, enhSelGR, rpkmCountsSel, txsSel)
    inTadSig <- combineInTAD(inTadSig, tadGR)
    corData <- findCorrelation(inTadSig, method="pearson")
    plotCorAcrossRef(inTadSig,corData,GRanges("chr15:25000000-28000000"))
