injection order scatterplot — plot_injection_order • metabolomicsR

Injection order scatterplot. The `@sampleData` should be sorted by injection order, with a new column `ID` from 1 to N.

Usage

plot_injection_order(
  object,
  color = "NEG",
  shape = "NEG",
  size = 0.6,
  ID_order = "ID_injection_order",
  feature_name = NULL,
  random_select = 16
)

Arguments

object: A Metabolite object.
color: A column in `@sampleData` to show the color of points.
shape: A column in `@sampleData` to show the shape of points.
size: Point size.
ID_order: Injection ID order in the `@sampleData`.
feature_name: A vector of selected metabolites to plot. If NULL, will randomly select 16 (default) metabolites to plot.
random_select: An integer, number of randomly selected metabolites to plot.

Value

A scatterplot.
