mvTypePlot {DAPAR} | R Documentation |
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.
mvTypePlot(qData, labels, threshold = 0)
qData |
A dataframe that contains quantitative data. |
labels |
A vector of the conditions (labels) (one label per sample). |
threshold |
An integer for the intensity that delimits MNAR and MCAR missing values. |
