wrapper.mvImage: Heatmap of missing values from a 'MSnSet' object

In samWieczorek/DAPAR: Tools for the Differential Analysis of Proteins Abundance with R

Heatmap of missing values from a MSnSet object

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

wrapper.mvImage(obj, pattern = "missing MEC")

Arguments

obj	An object of class MSnSet.
pattern	xxx

Value

A heatmap

Examples

utils::data(Exp1_R25_prot, package='DAPARdata')
obj <- Exp1_R25_prot[1:1000]
level <- obj@experimentData@other$typeOfData
metacell.mask <- match.metacell(GetMetacell(obj), 'missing', level)
indices <- GetIndices_WholeMatrix(metacell.mask, op='>=', th=1)
obj <- MetaCellFiltering(obj, indices, cmd='delete')
wrapper.mvImage(obj$new)
