mvImage {DAPAR} | R Documentation

## Heatmap of missing values

### Description

Plots a heatmap of the quantitative data. Each column represent one of the conditions in the object of class `MSnSet` and the color is proportional to the mean of intensity for each line of the dataset. The lines have been sorted in order to vizualize easily the different number of missing values. A white square is plotted for missing values.

### Usage

    mvImage(qData, conds)

### Arguments

`qData` | A dataframe that contains quantitative data.
`conds` | A vector of the conditions (one condition per sample).

### Value

A heatmap
