Source: R/qc_visualizations.R
plot_injection_lm.Rd

Plots histograms of p-values from linear regression model, where each feature is predicted by injection order alone. The expected uniform distribution is represented by a dashed red line.

Usage

plot_injection_lm(object, all_features = FALSE, assay.type = NULL)

Arguments

object

a SummarizedExperiment or MetaboSet object

all_features

logical, should all features be used? If FALSE (the default), flagged features are removed before visualization.

assay.type

character, assay to be used in case of multiple assays

Value

A ggplot object.
