### Description

Computes and display correlation plot for samples within MSnSet

### Usage

    corrPlot(
      MSnSetObj,
      addValues = TRUE,
      title = "",
      low_cor_colour = "#FFFFFF",
      high_cor_colour = "#B90505",
      low_cor_limit = 0,
      high_cor_limit = 1,
      textsize = 3
    )

### Arguments

`MSnSetObj` | MSnSet; an object of class MSnSet
`addValues` | logical: adds correlation values to the plot
`title` | character; title of the plot
`low_cor_colour` | colour; colour for lowest correlation in scale
`high_cor_colour` | colour; colour for highest correlation in scale
`low_cor_limit` | numeric; lower limit for correlation in colour scale
`high_cor_limit` | numeric; upper limit for correlation in colour scale
`textsize` | integer: set the size of correlation values text

### Value

An object created by `ggplot`

### 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
    corrPlot(MSnSet_data, addValues=TRUE, title="Correlation plot",
        low_cor_colour="yellow", high_cor_colour="pink")
