Plot feature intensities across run order — plot_scatter_omics

Generates scatter plots of feature intensities against run order from a long-format data frame. Points are coloured by plate and styled by QC status. Optional vertical lines indicate batch boundaries.

Usage

plot_scatter_omics_feature(df_long, title = NULL, batch = NULL, point_size = 1)

Arguments

df_long: A long-format data frame produced by OmicsProcessing::prepare_df_long().
title: Optional plot title.
batch: Optional character scalar specifying the batch column. If provided, vertical dotted lines are drawn at batch boundaries.
point_size: Numeric scalar controlling base point size.

Value

A ggplot2 object.

Examples

p <- plot_scatter_omics_feature(
  df_long = df_long,
  title = "Before normalisation",
  batch = "batch",
  point_size = 1
)
#> Error in plot_scatter_omics_feature(df_long = df_long, title = "Before normalisation",     batch = "batch", point_size = 1): could not find function "plot_scatter_omics_feature"
print(p)
#> Error: object 'p' not found
