wrapper.mvTypePlot {DAPAR}R Documentation

Distribution of missing values with respect to intensity values from a MSnSet object

Description

This method plots a scatter plot which represents the distribution of missing values. The colors correspond to the different conditions (slot Label in in the dataset of class MSnSet). The x-axis represent the mean of intensity for one condition and one entity in the dataset (i. e. a protein) whereas the y-axis count the number of missing values for this entity and the considered condition. The data have been jittered for an easier vizualisation.

Usage

wrapper.mvTypePlot(obj, threshold = 0)

Arguments

obj

An object of class MSnSet.

threshold

An integer for the intensity that delimits MNAR and MCAR missing values.

Value

A scatter plot
