plot_chain_distribution: Plot logFC of lipids per class showing chain information

In lipidr: Data Mining and Analysis of Lipidomics Datasets

Description

Plot a chart of (log2) fold changes of lipids per class showing chain lengths and unsaturations. If multiple molecules with the same total chain length and unsaturation are present in the dataset, the measure is averaged, and the number of molecules is indicated on the plot.

Usage

plot_chain_distribution(de_results, contrast = NULL, measure = "logFC")

Arguments

de_results	Output of de_analysis().
contrast	Which comparison to plot. if not provided, defaults to the the first comparison.
measure	Which measure to plot the distribution of: logFC, P.Value, Adj.P.Val. Default is logFC

Value

A ggplot object.

Examples

data(data_normalized)
de_results <- de_analysis(
  data_normalized,
  HighFat_water - NormalDiet_water,
  measure = "Area"
)
plot_chain_distribution(de_results)
