(Invisibly) returns a reordered correlation matrix plot.

### Examples

    data(human_anno)
    data(exp3_OHT_ESR1)
    MSnSet_data <- convertToMSnset(exp3_OHT_ESR1$intensities_qPLEX1,
        metadata=exp3_OHT_ESR1$metadata_qPLEX1,
        indExpData=c(7:16),
        Sequences=2,
        Accessions=6)
    corrPlot(MSnSet_data, addValues=TRUE, title="Correlation plot")

    # change colours
