plot_chain_distribution {lipidr} | R Documentation

## Plot logFC of lipids per class showing chain information

### 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)
